Please assist me with jerky/stuttery video playback!

[ajm786]

Whenever I playback video, in general Divx files, they ALWAYS jerk and stutter. What happens is that it will look like the video is playing fine, but once you start getting into the video, you'll see momentary hitches every now and then. It looks like the video freezes, and then speeds up to catch up to the audio. The audio itself never hitches or stutters, it's only the video. CPU usage never goes above 25% at any time, so there's really no CPU spikes. I've tried everything, BIOS updates, video card driver updates, chipset driver reinstall/updates, sound card driver updates, uninstalling/reinstalling codecs, you name it.

What happened next is that when I went to work and tried it on my workstation, which has an Asus P5B, Core2 6320 and nVidia 8600GT, it DOES THE SAME THING!!!

So I tried getting rid of all codecs, and installed FFDshow. It seems better now, but every so often, I'll still get a momentary hitch.

FFDshow's video codec has a feature that will allow you to analyze the video stream. What I'm seeing is that whenever the hitches occur, the video stream will drop frames. It's directly correlated.

What gives, and how can I remedy this annoying behavior?

Thanks for all your help.

Use a different virus checker on both machines. Alternatively, a different spyware/rootkit detector.

I did that. Machines are both clean. I used both Spybot as well as Adaware on both machines. Both turned up nothing. Machines were checked and double checked with AVG Antivirus as well as Trend Micro SMB. No viruses.

^^^ mine did that too after I changed from ati x800 to 8600gt.... upgraded the psu with (stupidly) 17A @+12v.... is the recommended psu mininum at 25A?

I emailed evga about this and asking me to remove all prev drivers from my ati... which i did using remove hardware (shown the hidden driver and removed it) on windows vista HP32-bit

although mine is an emachine with ms 7184 mobo, amd64 3400+, 1gb ocz ddr400... i would think it would make my fps higher if i change the vid card, but it reali lags up my video, esp when i m using mpcstar and try to forward/rewind the movie.

any thoughts, guys?

I've got a Corsair HX620, so it's definitely not the PSU.

Video codec problems are sometimes difficult to solve. Try the Doom9 forums. Don't forget that it could also be a problem with your source divx files.

That's odd. Even a five-year-old computer can handle playback of DivX/XviD DVDrips. Hell, with an E6320, you should easily be able to upscale to 1920 horizontal pixels, enable full mplayer postprocessing and even the Blur & NR and Sharpen filters.

Try this: uninstall ffdshow, go to CCCP, download and run the Insurgent to detect any incompatible filters/codecs from previous installs (then remove them) and then install the CCCP. If you still have issues, it could be a problem with your source files.

If nothing else works, go to ffdshow's Decoder Options page and check 'Drop frame on delay'. That's the most I can think of right now.
