Audio/Video Stutter/Hesitation

slickwillie · Jul 1, 2009

In Win7, I experience a 'stutter' (very noticeable in the audio, less noticeably in the video) while playing ANY type of media. MKV, AVI, MP3, streaming (youtube, etc). I do not have this problem in Win XP. The problem occurs in both 32 and 64 bit versions of Win7 RC.

I have an ASUS m4a78t-e board w/ a Phenom 2 processor.

I am using a pair of ADATA DDR3 1600 modules running at 1333. The modules actually came in a pack of 3 (6GB = 3x2GB), but I am only running two of them. I noticed that the specs call them triple channel, but is that spec related to the RAM itself or the MB's ability to run in triple channel?

If my problem is as simple as replacing my RAM, then I am sold. My only question would be why is XP running fine w/ the same RAM on the same system???

thoughts?

thanks!

i'm having the same issue
tho i'm just having problems with video files
music works fine
triple channel is a MB feature
but it can't be related to ram really because nothing else is affected
my guess is it'd have something to do with the codecs but i'm really at a loss here

Both of you: what product(s) are you using to play multimedia files?

I tried Kantaris for a while - but it stuttered. I reverted (2 days ago, in fact) to using the Seven Codec package myself. Others prefer the CCCP or K-Lite. Either way, it will depend a lot also on your network usage (Larry Osterman blogged about this last year) and HD usage at the time of video playback....

i used both the cccp packages and the win 7 codec pack with no difference
also it doesn't seem to be limited to one codec as all the videos are affected regardless of codec
HD/network activity=0
well no more than is actually necessary for playing the video
in browser streaming is even worse when it comes to video playback (using firefox. didn't test it with any other browser)

I was having pausing problems and I found codec packs caused the issues (shark codec pack) and are just not needed in Win7.

All I had to do was install haali media splitter and I had to install AAC filter to get audio from some some files.

Thats it, There are a couple of videos I'm still having trouble playing though. but they could be old encodes. I'm still testing.

More info as you go along, trv, would be great.

I finally started getting a bunch of stuttering in the video (but the audio went perfectly fine) when playing the Battlestar Galactica disk from the newly acquired box set. It got annoying as the video shifted to catch up with the text every 3-5 seconds.

I now have a new install of W7 and will test again to see if it still occurs.

I had same problems with playing all kinds of videos in W7. I tried different codec, but got no luck. I had to switched back to XP for now and wait for solutions.

I had the same problem.

If you have a lot of media files, Win7 starts making thumbs for all those files, which leads to enormous disk i/o.

Just let it finish.

I also disabled indexing on all my media drives, as it was crippling my disks performance.

MS stated indexing wouldn't affect performance, but that's BS.

squonksc, how do you disable indexing?

In explorer right click on the partition you want to disable it for.

Uncheck the indexing check box below, and click ok or apply.
Wait until the settings are applied.

That's it.

rats - I thought someone here had the answer to this.

My system: brand new Win7 x64, 8gb ram, Intel i7 quad.

Problem happens regardless of the media player: WMP 12, or WinAmp 5.57, VLC. WMP and VLC make a blip noise during the stutter, WinAmp just has little micro-stutters. These stutters occur about every 1/2 second (pretty much a regular beat too).

The problem for me is it occurs ONLY on streaming audio. Does NOT occur on downloads of any kind: Youtube, m3u files, local mp3 files, etc. The audio that I am streaming works perfectly on the exact same network using my WinXP and Win2K pcs so I know that it isn't the source or bandwidth. M3U files load smoothly and easily outpace the playback, as do youtube files.

Tjoe · Jan 29, 2010

Okay - now for the kick in the pants...

I opened a VM session of XP, launched WMP (it had to validate windows to finish install of WMP 11) and the sound is now perfect!

so... is it a quad-core issue? I know that there are some Quad Core issues with audio. I run an internet radio station and use Spacial Audio's SAM Broadcaster. Someone in their forum found an issue that directly related to multiple core processors. However, that bug caused the cpus to max out and the patch was specific to the program (SAM).

AngelProcesser · Jan 29, 2010

How many channels are running in both cases? Is this the same?

Tjoe · Jan 30, 2010

just regular stereo - 2 channels. That's what you were asking, yeah?

Your question sparked something else in my head though: DirectX. Win7 has version 11 and the VM session of XP is showing version 9. Could this be a DirectX issue? My IT guy is testing to see if this is a 32-bit vs 64-bit issue.

AngelProcesser · Jan 30, 2010

Please list your audio equipment.

Also, indexing first has to index and with large disks and libraries this can take time.

You can review in indexing options if the index has completed building or not.

I do not suggest turning it off.

Hello all

Just to add to this discussion, I have an ATI HD 5770 1GB and I am also suffering with stuttering videos.

My full specs are a follows:

Gigabyte GA-EP45DS3P Motherboard
Gigabyte GV-R577D5-1GD Gfx Card
Intel Core 2 Quad Q9650 @ 3Ghz
Windows 7 Ultimate x64
8GB DDR2 Ram (4-4-4-12)
2 x WD Caviar Black 1TB SATA HDD
LG SuperBlue BD Drive
Dell SP2309W Monitor

All my Drivers are upto date including BIOS, Chipset, Monitor, Gfx, Devices, Software etc.

No additional Codecs installed.

I am having problems with Movies which are stuttering, i.e. every couple of seconds it looks as though a frame is dropped, this happens all through the Movies, and makes them very uncomfortable to watch.

I have tried Quicktime, Media Player, VLC, Media Center and all have the same problem.

I am seriously considering installing XP Mode in hopes this will solve the problems I am having.

Thanks in advance

Kevin

kncowans,

Your hardware seems well above what is required for excellent HD video using WMC. Did you do an upgade to W7 or was it a new install?

I would review if all the required HD componenents have the latest drivers by checking the manufacturers website.

kncowans · Jan 31, 2010

Hello

The computer is a new build and Windows 7 is a clean install.

All Drivers are upto date.

Thanks in advance

I have a similair set up and have no issues with 1080P MKVs, even those exceeding a bitrate of 16K w/Win7 64

The only difference is I use Haali splitter and ffdshow (or Hardware acceleration), not Win7s built in.

Have you tried this to see if helps any?

kncowans · Jan 31, 2010

Hello Wishmaster

What would I need to setup ffdshow and the Haali Splitter?

Thanks in advance

Kevin
