Sync audio error in Virtualdub converted files

[Sibaris]

I use VirtualDub to convert avi files to divx, in order to play the movies in my domestic DVD player, which can only read the divx format. If the avi files are VBR, I first save the WAV file and recompress it to a MP3 CBR audio. The converted files are OK and they plays fine, excep if I fast-forward the file, in wich case when I play in normal mode again, the audio and video have lost synchronization. This problem also occours playing the converted files in my PC with the Windows Media Player. Anyone can help to avoid this problem in the conversion process??
Thx

Dropped frames during capture will cause audio/video sync problems. I would monitor the dropped frames count during a capture. Also using mp3 compression on the audio can contribute to the sync problem. At least that is what I have encountered when using virtualdub. Try Dr. Divx, I have had excellent results with that program.

Also using mp3 compression on the audio can contribute to the sync problem

well, VBR MP3. and only in AVI

sibaris: use AVI-Mux GUI. extract the audio, use belight to encode to CBR MP3 and mux it again
