I did a 3000k bitrate mpeg1 capture of a 2 hour several long video from VHS vcr.

the original mpeg1 file has perfect a/v sync.

I encoded it to divx using VirtualDub 2 pass Divx5 650k video and 64k div- audio.

when I play the encoded files near the end the audio would be 2 seconds out of sync...

anyone have any idea why? and how to correct it? any program that will let me encode with perfect a/v sync?

thanks in advance for your help
