Q: Solved: DVD audio and video playback is jumpy

Hi Guys, im having a bit of a problem with my dvd player on my laptop. the laptop is a Dell XPS M170 running XP pro and the dvd player is an HL-DT-ST DVD+-RW GSA-T21N. the original died a few weeks ago and i got a replacement part under warranty. the problem is that now i can not watch films. i get about a second or two then it will pause for a second or two. I have updated the firmware and drivers, i have also turned the hardware acceleration on and off. this playback problem occurs in both VLC and Windows Media Player which both worked with my previous drive. its starting to bug me now and any ideas would be great although i am starting to think that perhaps it is a faulty drive and i should get a new replacement??

When i try to watch a dvd on my computer it seems to be overwhelmed and seems like it has to pause to buffer every few seconds.
When i bought this pc DVDs played just fine, now it sorta skips/jumps while playing because it freezes for an instant every now and then. This affects everything, including the mouse, but only while watching a DVD.

Its like the drive doesnt keep up with the computer, but the processor never goes above 90%
so i know its not maxing out and hanging because of that.
Maybe i need new drivers? But idk where to find them.

Hi , I recently burnt my first DVD using Nero 7. All seemed to go well , very easy to follow instructions and burned in about an hour.

However , when playing back the DVD in my player and on WMP the image is ever so slightly jumpy. Id say approximately every 2 seconds the film seems to pause for a fraction of a second then continue. The quality other than this is excellent.

Can anyone please help me with this problem as its pretty annoying.

Hello, since I started my computer yesterday, I experience the following problems:
in Chrome and Firefox, videos stop playing, lose sound or reset at random times (could be after a few seconds or several minutes). It happens with both Flash and Html5 videos, and on all sites (Youtube, IGN, Gamespot, etc.). I have to close and reopen the browser tab to be able to play the video again... then the same problems occur again.
In Spotify, music stops playing randomly as well. Changing track doesn't fix the problem, I have to restart Spotify.

Here's what I have tried:restart the computer many times
Uninstall / reinstall Flash
Disable Flash in Chrome plugins
Disable hardware acceleration in Flash
Uninstall Camstudio, the only software I installed recently
Run CCleaner and clear caches
Try on Firefox (which is clean, I never use it), same problem
Reinstall Chrome
Reinstall Spotify

This is my work computer, running Windows 7 64 bit Enterprise SP1 and it has the latest Windows updates.
Thanks in advance

Hello. Recently my DVD drive won't play dvd's or cd's correctly. There is a contant skipping. It's laggy and the video chops and the audio is all choppy as well. I've tried reinstalling drivers and doing all kinds of things but can't figure it out for the life of me. I can still burn dvds/cds and play games etc no problems, but playing back dvd videos or cd audio, its a choppy mess. Does anyone have any ideas how to fix this?

Edit: My drive is just a basic Sony DVD/CD+R/RW/DL... all in one drive.

I am having a problem playing audio cds or dvds on my computer. I have tried playing music cds in Windows Media Player 9 (its Windows 2000) as well as VLC. It seems like the music is playing a lot slower than normal. With dvds, the audio and video studders and delays as it plays. I have a Samsung TS-H552B dvd drive and a Sony CRX215E1 cd drive. Everything is delayed the same way for both drives.

The comp:
Asus A7N8X-E Deluxe mobo
AMD Athlon XP 2600+
Samsung TS-H552B DVD+-R/RW
Sony CRX215E1 CD-R/RW
Creative Sound Blaster Live! 24-bit Sound Card (with updated drivers)
Windows 2000 with all updates

Anyone know of a fix for this?

A:Solved: Slow audio/video playback from CD/DVD drive


I assume that both drives are on the same cable (Secondary IDE)

Go to Device Manager open the small + sign beside IDE controllers double click on the Secondary IDE and then in the new window click on the Advanced Settings and check that the Transfer Mode is DMA if available and Not PIO and that the current mode is DMA.

Hello. I have some audio issues that are causing distortion whenever I watch videos on youtube or watch streams on twitch. I updated my flash and that didn't change anything. These issues just started within the last 3 days. I tried a system restore from two weeks ago and that didn't work. I double checked my sound drivers and they are up to date. This happens in both Firefox and Google Chrome. I started Firefox in safe mode with all addons disabled and it still happened. The distortion didn't really capture very well on the video even though I can hear it. You can hear it better in the beginning. And this happens on videos that are buffered, even if I wait 5 minutes, this still occurs. I can try a different video once I get back from school(have to leave right now) if you want to hear the distortion better.

Got a dvd rw drive and installed it recently (sony dru-710a).

Drive seems to work properly, it can read disks, burn to dvds, etc.

When i try to play a dvd movie in it though, the playback is jumpy and irrelegular. Seems that it is causing my cpu to work at or near 100%, and i believe that is causing the bad playback.

Ive made sure that DMA was enabled for the drive. Ive also tried using multiple software packages for playback, with no real difference. Ive made sure the dvd itself is not faulty.

Systems spec:

amd 1.6ghz processor
512 mb ram
gf4 mx440 3d card
windows xp pro

Anyone have any ideas?

Alright, I have spend about 3 years trying to resolve this problem and I have done so much research that I felt it would be a waste for me not to post something about it. 
After I owned two Dell laptops, the XPS13 and Alienware 17. Both having the same problems. I tried everything, I read through all of the forums and I tried everytthing these forums have suggested and at multiple occasions I ruined my laptop and had to format it. 
I also always had the full warrenty with Dell customer service and have replaced my xps13 TWICE and my Alienware once. This is of course after replacing the motherboard and the hard drive and spending endless hours over the phone with them while they update all my drivers and ensure my software is running correctly. They ran 100's of tests on my computer to see why this is happening and no one could ever solve this problem. 
However, after all this research with no solution in sight I thought of the problem logically. My alienware was running 16 gb of ram and 1 TB of HDD regular hard drive. I figured if I have so much ram to run anything I want, maybe it is having the regular hard drive that is not keeping up with the ram. Sure enough, when I went and bought the best SSD out there Samsung Pro 950 256 GB and installed it and used it as my operating system while the HDD ran as my storage. For the first time in 3 years and 4 computers... my pc was running with no jitterz or lagging or any issues!

I have the annoying problem of having jumpy mp3 playback. When playing MP3s of my hard drive they occassioanlly get jumpy. Almost as if my computer is running out memory or processing power. Video play back (from the same hard drive), games, and applications never have a problem.

My system is:
AMD Athlon XP 3000
1024mb ram
Windows XP
Motherboard sound card
Radeon 7200 Video card (64mb)
Usually playing back mp3 with itunes

I know my processor and ram are more than enough to handle anything (at least as simple as mp3 playback). Could a problem with my video card or my crappy sound card be causing the problem?

I am assuming the answer to this question is no, but can having a large library of mp3s (25gb) cause itunes to have a problem?

Is there anything in windows xp settings that i can adjust to make the playback smooth? My laptop which is a g4 ibook handles the same mp3s without a problem. I think i have most unneccessary services disabled in windows.

Is there any utility that i can use to determine exactly what program/process is accessing my hard drive/processor/memory the second there is a skip in the mp3 playback?

I really want to fix this little problem, but i am just not sure what the most likely culprit is.

Just recently i noticed that i am getting no audio output when i watch any type of video. When i select troubleshoot sound problems it tells me: "Enhancements might cause audio to stop working properly, turning them off might improve sound quality. To turn off enhancements, check the box labeled "Disable All" or uncheck them individually in the list and click "Apply". If you don't see an enhancements tab then this audio device doesn't support configurable enhancements." I have none. So then i  see under controller information there is an option to uninstall the driver when selected. The first time it worked after rebooting. Now, im having the same issue and nothing is working. When i check my speakers i can hear sound. and i also can hear the computer notfications. This seems to only be happening when i try to watch videos ( like youtube)

A:No audio during video playback

@Jshanklin85 Hello;Allow me to welcome you to the HP forums! Videos have their video and audio parts encoded using something known as codecs.  These codecs are required to be integrated into the media player you are using. You have not told us (1) which OS version you are using, or (2) which media player you are using -- and without this information, we don't have the information we need. We can proceed when you provide the information.Thanks

O.S. is Windows XP Media Center Edition (same as XP with extras). My Windows Media Player & RealPlayer were working fine until very recently.

Now, when I playback known good commercial &/or home movie DVDs using Windows Media Player or RealPlayer, I can hear the audio OK but there is no video.

If I playback the same DVDs on the same PC using VLC Media Player, a stand alone Sony DVD player or another PC, both video & audio play OK.

When playing back movie files stored on HDD, both W.M.P. & RealPlayer will play both video & audio in AVI files but will not play the video if the file is an MPEG.

In trying to troubleshoot this issue, I had a hunch that it might be codecs related. Using another PC (that still plays DVDs OK - with nearly the same software installed) I was able to compare the installed video codecs as shown in the Device Manager.

A glaring difference between the two machines was the "no playback" one had an additional codec called fps1. This reminded me that the "non-working" PC had FRAPS software installed which also installs fps1.

I thought that uninstalling and manually removing fps1 from the registry & Windows files would fix this but I thought wrong! Although all traces of FRAPS & fps1 were gone, there was still no video during playback.

Other than a backup/restore of the out-of-date working system to the non-working one, I'm at a complete loss. If I can avoid doing... Read more

This may be due to a codec problem.

Hi there

I have an RM CY25 laptop (Samsung manufactured) running Windows XP, 80GB IDE HDD, 2.0Ghz Intel PM CPU, 764MB RAM.

I use it for DJ-ing at parties etc.... Well i was GOING to to use it but the music playback is terrible when i use my DJ program (OTS DJ) If i play through windows media player its is slightly better but i need to play it through my DJ program. The program is fine as alot of my DJ friends use it with no problems.

I updated my sound driver (AC'97 Realtek) to the most recent 2008 version. I checked the hard drive for errors using MHDD 4.6 and there are no slow sectors. I checked for Viruses using AVG and non were found, i tried a different CPU and still the same! Im currently running Memtest86+ on the RAM but it seems fine and its nearly done testing.

Im totally stumped, im quite proficient with computers but this is really bugging me and i can't seem to fix it. Anyone had any similar problems or has any ideas to fix this issue?

Only thing i can think is that the motherboard is faulty but everything else on the laptop works fine, besides, i dont want to fork out for a new motherboard!

Any ideas would be much appreciated

So this problem has been happening to me for a while now. Randomly while playing a few video games, all sound shuts off. I dont get sound from the game, or youtube, or itunes or anything. In sound, my speakers are registering the sound as the green audio bar is moving, it just isnt playing. Also it causes youtube videos and other media to play very slowly. They are fully buffered, but it moves much slower, with no sound. The only fix is to restart my computer.

Ive done a lot of searching around and there are a lot of people who get this problem, at different times too. The problem is that it is so random and hard to reproduce. Everyone also seems to have different fixes and workarounds, but none of those work for me, except the reboot of course.

People suggested disabling and reenabling speakers, reinstalling drivers, and also restarting the windows audio service. None of those worked for me but I did notice something. If I disable the windows audio service, or ended the audiodg.exe process videos from youtube and such would start playing at normal speed. They didnt have sound of course, but they were playing at a proper speed. Then when I restarted the windows audio service the videos played slow again.

Im at a loss and have no idea what is going on. While there are other threads about this problem, I decided to make a new thread with a bit of updated information. I hope someone out there could shed some light onto what is going on.

So lately I've been noticing that within 15 minutes of starting up my PC audio and video playback works fine. From time to time it works perfectly longer but it's once in a blue moon. But normally once the 15 minutes (or so) are up, audio playback stops working entirely. Recently it's been a problem with video playback too! Like I would go on youtube and the video I would play would be stuck on 0:00 or whatever time I may or may not skip to.

The sound problem is not limited to files on the web because when I open videos in VLC media player the video remains silent despite the sound being on. However, the video usually still plays.

Something else I've noticed is that when I go to the Control Panel > Sound > Configure > Test, it tells me that the device (speakers?) are being used by another program. And if I have headphones plugged in while the audio is still working, a message will eventually pop up telling me that the headphones were disconnected (despite them sill being in there) when the audio stops working.

Oh and this thing is an ASUS Vivobook S400CA, all hardware is the normal factory stuff. I've tried fixing my drivers by downloading those on the ASUS website. I was going to run drivertoolkit to update multiple drivers that may or may not have been problematic but I didn't want to pay the $20-30 before I know that this will fix things.

Hello all,

Whenever I playback an audio or video file, regardless of format or player involved, I get skipping and pauses whenever the hard drives are accessed or have anything running in the background. An example is if I start listening to music or watching a video file, I can't do anything else without it interrupting the playback. The video and/or audio stops for a split second and all I hear is a playback of that split second for a second or two and then play resumes. It is completely random as to when it happens but it seems to happen most when the hard drives are accessed. I have tried reinstalling Windows and removed all process that I am able to. I try playing them off both hard drives and that doesn't make a difference. Nothing is working.

I'm pretty sure my specs are fast enough to multitask so if anyone has any suggestions, I would love to hear them. Thanks!

A:Audio and Video Playback Problem


This is a nice problem, I'm glad I don't have... Well the first thing that comes to mind that could be the problem would be your inferior onboard sound card...

But there are a couple of things you can try before buying a SB! live...

1) Run "msconfig" and remove EVERYTHING from startup, restart and test
2) Press ctrl+alt+del and click performance and play your media again
3) If your CPU usage isn't 100% all the time it might be a software problem then...
4) Find updated drivers for your sound card...

Okay it does seem that everything is on par but I'm going to speculate here that sometimes I have found to be the problem with some of my clients...

1) Remove your secondry HD and any CD/DVD drives
2) Put everything on CS (cable select) and your primary HD at the end of the ribbon cable on your primary IDE channel
3) Test

Tell me what you've found...
Good luck...

So basically the sound and video on my machine has gone kaput and I can't figure out why.

I've updated GeForce video drivers, Realtek highdef audio drivers and uninstalled and re-installed the ASIO4ALL to see if maybe that was causing the issue.
Any help is greatly appreciated! I'm a bit stuck here...
*Edit: Just played some FRAPS footage that is *.avi format and the video playback plays through, but the sound cuts out after a second. I'm thinking it's definitely a sound issue.

This has been happening for a long time, but it's really starting to drive me insane now.
I noticed it happens more often the longer the computer has been on for. It happens whether I'm playing a downloaded video or streaming something through a browser. I suddenly hear the audio make a crack sound.. sometimes it can go about a minute without making it, but more often it happens every 10-20 seconds.
Through googling I think it's called a DPC latency problem?

Through my google searches I saw people were trying to figure out the problem through a program called LatencyMon, so I downloaded it and ran that and Latency Checker. I've included some screenshots after running both of these programs for some time in the attachments along with my DxDiag information. I tried to understand what LatencyMon was saying, but I couldn't really get it except for that "USBPORT.sys" and the others at the top could be the sources of my problems (I think?).
Please let me know if you need any other information to help solve this problem.

Thank you so much for any help!

I've noticed for the last couple of weeks that when I listen to audio or video (YouTube, Amazon Cloud, Windows Media Player, etc.) that the sound/video is slow, choppy and popping. I'm not really sure what caused this because it was working just fine. Internet browsing works just fine, pages load good...even with a few tabs open. An ideas on how I can fix this?

A:Audio and vIdeo playback is choppy & slow

What antivirus/antimalware software to you have installed? What are your computer specs?

Is it possible that a problem in the voltage going to the quartz crystal on the motherboard can cause audio/video to crackle/stutter?
I suspect the quart crystal or it's power conduit/source because I'm also noticing intermittent slow time (from 5-10 minutes an hour some days but as high as half hour lost in one hour) and my download speed (kb/s) "increases" (says I'm getting at 9kb/s on a dial-up fax modem when I normally only get the normal 5.9kb/s MAX when working normally). 20% of the time the BIOS time will also be slow when I look (reboot).

Or could it be something else? Other symptoms include the computer will freeze after being on for several hours/a day and though the mouse moves I can't open/switch to task manager (clicking on it in the taskbar will only cause it to highlight but not maximize/ same with any other program like FireFox), or select the shut down from start menu or even shut down via the power button 5 sec hold. (I have to power down the power box). It will still freeze sometimes on reboot after a cool down.

I don't think it is XP since I recently did a repair install of XP after losing safe mode ability and in an attempt to fix the intermittent audio problem (I had not noticed if the time was acting up prior). - Have yet to do a clean install though

CPU temps appear normal in both BIOS and PC Wizard 2010 (3 degrees C difference after complete boot and load - highest temp in PCWiz is AUXTIN temp which averages 45-... Read more

Hey guys.
I recently desc covered that besides VLC on my laptop all the other video player are not able to work properly (meaning,, Windows Media Player 12, Cyberlink PowerDVD12 and WMPC are able to play only the audio, but not the video, just black screen),, BUT with VLC is no problem playing any video format!! The thing is that I didn't have this problem previously,, all my video players were able to play all the same video files, which they can't now!
I have the latest AMD Radeon HD video drivers installed (just after I discovered the problem).
Can anyone help me with this?
Thanks and have a nice day, hope we can resolve this. ))

A:No video playback only audio (black screen)

If it works with vlc tans nothing else, then I doubt it's your video card drivers. However, it may be the codex used by the different players.

Can you just use vlc? Are you having any other graphical issues?

The audio and video playback on my laptop seem to be malfunctioning - as I use other programs and/or surf the internet, any video/audio playing at that moment will scratch, hiccup, and generally sound as if it's coming off an old-fashioned vinyl player.

If I'm not doing anything, however, the audio/video will run fine - it's as if the more CPU power is used for other tasks, the audio/video suffers. This, however, has not happened before.

Hardware: Sony VAIO Laptop VGN-SZ Series
Operating System: Windows XP Professional, SP2
Basic Specs: 1.83 GHz CPU, 1.00 GB RAM, functional sound card (SigmaTel Audio) and graphics card (NVIDIA).

Recent potential sources of problem:
1. Recently went through a slew of defragging, virus/malware scanning, and installing/uninstalling various anti-virus programs (i.e. BitDefender 2009)
2. Installation of various RAM and CPU optimization tools (Uniblue Powersuite, RAMSaverPro).
3. Destruction of the infamous Vondu Trojan (as many as 48 separate variants were discovered and deleted).
Any advice, or help, please?

A:Audio / Video playback hiccupping and skipping

I've done some searching around, and it seems to be the case with laptops that sound cards are often attached directly to the motherboard/CPU unit, so if something's throttling back the CPU, the sound/video will accordingly suffer.

That led me to look for anything that could be causing my CPU to slow down... But I can't seem to find any.

I've run Kaspersky's Anti-Virus suite, I've done Uniblue's Powersuite (including Registry Booster and CPU Optimizer), Malwarebyte's Anti-Malware scanner - and I've come up with several registry fixes / malware that I've removed, but I've seen no appreciable improvement in CPU speed.

In the Task Manager, my CPU usage flutters around 50 to 60 percent, which doesn't seem to be unreasonable at all - yet my CPU slows down. The tasks that take up the most memory are Firefox, Kaspersky, and one of my Yahoo Widgets (the Informer bar).

Everything suffers, I've noticed. Acrobat files load slowly, Firefox goes slowly, audio/video across all applications and browsers loads slowly, Photoshop is abominably slow, and don't even get me started on MATLAB's loading times.

Windows booting/rebooting time suffers, hibernation/sleep mode time suffers, and shutting down time suffers.

Should I run a HiJackThis scan and post it here, for more assistance?

Checking my audio quality levels, I noticed my default setting was 24bit 48000hz (studio quality.) Is that a setting I should continue using?

The only sound output device i'm using are only a pair of Skullcandy ear phones, in-regards to that i'm assuming such a level isn't needed for playback.

So can anyone recommend me a level I should use that will be the most appropriate for my earphones?

Please respond as soon as possible.

Thank you in advance.

A:The audio quality I need for video and game playback.

That's very dificult to say, it depends on to many factors. From how sensitive your ears are to how detailed sound in games is. It could be different in different games. Best thing is to keep lowering until it's unsatisfactory for you. I don't think it matters a lot to game's performance, if that's what concerns you. Those settings for sound are all "up to", if something is recorded in low format, no settings in reproduction are going to make it better.

HI there,

I'm having terrible problems with my machine. I upgraded the memory thinking it was that causing the problems.

With no real change I'm starting to wonder if the machine is infected and I just can't find it.

Even typing this I'm watching the charaters appear one by one.

The main problems are as per the title.

Can you see anything that I can't?

A:bad audio/video playback high cpu processes

Hello huglebass,

How long ago did this issue start?

Hello everyone
I'm Bidi, this is my first post in this forum.
I was wondering if I can get help with an issue.
It's been a long time, probably 1 year or 2, with the same issue.. 
There is this occasional audio glitch that happens every now and then, whether it was audio playback, or a video I'm watching online or offline.., the video also glitches that same split second, and then it plays as normal without any audio delay; video and audio stay in sync.
Also it glitches several times when the clock hits 12.00 am, and that's when it hits the hardest, so I always wait till a minute passes and then continue on watching/working.., like after 12.01 am..
My Speccy screenshot link is : http://speccy.piriform.com/results/wn6Z5KsPYgi53NcM8HIRV8n
My Minitoolbox report is attached below as well :
Hope someone would help me with my issue, and any recommendations/advice on improving my pc's system like redundant software installed or ways to make my pc faster would be greatly appreciated.
Have a great weekend gentlemen.

The thing is that I didn't have this problem previously,, all my video players were able to play all the same video files, which they can't now!
I have the latest AMD Radeon HD video drivers installed. As I mentioned I didn't have this problem before,, with a previous versions of the AMD graphics card driver. This happened to my laptop a while ago already,, since I have this problem I updated my video drivers 5 or 6 times at least, and no change so far !!!

As I mentioned I have the problem for some time already, during this time I re-installed my Windows couple of time, plus I even changed the version of the windows (7to8), for the moment I have the last version of video driver installed, I haven't installed ANY codecs
Can anyone help me with this pleas?
Thanks and have a nice day, hope we can solve this. ))

A:Black screen while video playback (Audio only)

Can you simply give us an example of a video extension that will not play anymore in WMP, now that you have upgraded to Winn 8 and done several graphic driver updates in an attempt to fix your issue (eg, .avi files, .mpg files, etc)? It could very well be that the original codec is no longer supported in WMP but the fact that VLC works Ok tells me that your graphics' driver should not be the issue.

Has anyone else noticed and/or fixed this issue? It seems that sometimes when I'm watching a video (usually in Media Player Classic) or listening to music (in MediaMonkey), sometimes when I pause playback, after resuming, the volume seems to increase significantly. I don't recall having volume issues before on this computer when it was running Windows 8.1, so I'm suspecting this is a Windows 10 issue. Just curious if it's a known issue or if it's just me and my setup.

A:Hard Drive interrupting audio/video playback *HELP ME*

Hi rosko, welcome to TSF..

has this problem just started happening or has it suddenly got worse?

Have you recently scanned for malware?

Could you provide any details of any codec packs you have installed please?

Do you have any programs which 'index' files (nero scout etc)?

Also, if you log off your profile and onto another one, does the problem still occur?

Don't know what I've done. Wanted to do a video recording using "camera" from my windows desktop. Got tinkering in my audio settings to eliminate background noise cause there was all this "whooshing" wind type sound during playback. Now I have NIL volume on video recordings I do with my computer's app. The playback is so faint...I have done everything I can think of with the DTS audio...put the microphone up to 30.0+ decibels (the dot on the slider is at the top). I've gone into my realtek settings & everything is on full volume. I can't figure this out...I should be getting normal playback-full volume on sound like I was before I got adjusting the andrea filters to eliminate background noise. I unselected all of those, experimented with checking & unchecking one thing or another...still the same. I barely have any volume on playback yet all the volume bars are at 100. It makes no sense...I want to do a video message for my daughter who's expecting her first child to pass along some information about what to expect when you're expecting...& I've completely screwed up my sound recording. Even selecting to restore to defaults has had no effect.

A:messed up audio playback/microphone with video recording

If you have a System Restore point that is BEFORE you did whatever you did, use that as it should fix it.

The error message for Quicktime shutting down will have Chinese? characters in it. I find this interesting in light of the facts I'm white and live in Chinatown.
This came up, a Quicktime error, Error-36 an I/O error occurred.
I've installed programs, shuffled files, done many every day operations in the past few weeks and days including downloading stuff I think I'm allowed to.
Not recalling any other specific issues other than a general slowdown. If I have one, my malicious scumbag sense is tingling.
I haven't really tried much yet beyond running basic scans, Avira free and adaware.
If this is really of interest to one of you guys, as it is to me, I'd like as much technical jargon thrown at me as possible after we figure it out.
I really dig this stuff and am not discouraged by things not working. Like getting beat up by a bully and not knowing how to fight as a small child.
I won't understand it all, but I'll pick away at it. Thanks, some day I'll have my chops and be able to contribute like you swell chaps are.
