Audio-Video desynchronization (again) (vs. VirtualDub)

Can you help me with this please - I rendered captured film from TV. It takes me about 15 hours and in the result the audio and video are desynchronized. I put the video in DivX and audio in MPEG Layer-3. I think that the main problem is in MPEG Layer-3 codec. I tried to compress 10 000 frames with the same settings (and with the same result) and then I set GSM as audio codec (good quality and low bitrate) and the audio was OK (synchronized).
But when I compress it in VirtualDub (to DivX and MPEG Layer-3) it is synchronized too.
Can you tell me why please, or how to make it synchronized. Thank you.

No answer... OK. I solve it this way (maybe helps somebody):
In Vegas Video I render to avi without audio. Then I render audio only to wav. Then I open avi file in VirtualDub - set video to direct stream copy and audio as source wav file (that file rendered by Vegas Video) and set MPEG Layer-3 compression. After saving it in VirtualDub everything is fine! Bye.

There is a known issue with variable bit rate MP3's. Perhaps that was the problem.

I don't think that it's because of variable bitrate. When I am rendering avi with audio I can select MPEG Layer-3 but there is no option to choose constant or variable bitrate. The choice is available only when rendering to mp3 only.
