I know there are a lot of posts on AV sync problems, but for some reason, I can't get any straight info out of them. Here's the situation. I have several avi's with audio out of sync. It doesn't happen right away, but it sort of degrades as the movie goes on. I have virtualdub, but I can't figure out how to use it to fix the problem. Any help would be greatly appreciated.:angelgrn:

What is the speed of your CPU? That would be a good indication. Another useful things would be the resolution of the movies you're attempting to play.

I've got:

PIII 450
256 MB RAM
Voodoo3 3000 16MB VRAM
WIN 98 FE

I'm trying to run these movies in my native 1024x768 res.

EDIT: I just tried turning down the resolution on the playback, and I still get the same A/V sync problem.

If you have Windows Media Player v.6.4xxx installed, while the movie is running, right click in the video image. Select "Properties". Click on the "Advanced" tab. Select the DivX codec. Move the CPU slider. Click on "Apply". Click on "OK". Go back to your movie. Adjust the slider as necessary.

I have windows media 7. Is there anything I can do to the files to make them play a little better?

No, with WMP7 you can't modify the codec properties.

But you should be able to run wmp 6.4, by selecting 'Start'->'Run' and type 'mplayer2.exe' in the text box and click ok

It is certain that your CPU is a tad too slow. The higher the resolution of the movie (No! Not your screen resolution), the more likely the playback will jerk and go out of synch. Following the above suggestions should alleviate the problem. WMP6.4 is a faster-performing player than WMP7, as a final note.

Use GDIVX, Yahooplayer. Reduce color to 16-bit and resolution to 640x480.

I think I can help you with your sync problem. I have an AMD k6-2 400 mhz (256 MB RAM, GF2 MX400 64MB) and used to have A/V sync problems with some divx-files (res. 640x352, about 1hr long).

Try this, it helped for me!
Open the file in Virtualdub, set video to direct stream copy, set audio to full-processing mode. This way the audio will be encoded in PCM (no compression) and the sound-playback will require less from your CPU, leaving more capacity for divx-decoding. The file that will be created will be around twice the size of the original divx, but processing takes about 10 minutes..
By the way; use BSPLAYER

Please notify me if it works for you!!
