sync of vbr

[hbuyer]

I am trying to create a vcd from a divx movie created from a dvd.
When I exctarct the wav file in virtual dub and encode with tmpgenc the sound is out of sync.
I have tried adjusting the interleaving ms in virtual dub and also adjsuting the audio gap in tmpenc but neither seem to work.
My guess is virtual dub is having trouble extratcing the vbr mp3 so the probalme rests in the wav file. (the divx plays fine with sound synced)
As the divx has dual tracks vbr mp3 and ac3 I tried extracting the ac3 track in nandub but it just crashes.
I have also tried to exctarct the aduio track in premiere, media studio and sound forge, all refuse the divx format.
Besweet also does not want to handle the divx file.
How can I correctly extract a valid wav file (or ac3) to encode with tmpgenc?
Or is my problem something else (note I have tried this with a couple of divx files with vbr and the same occurs):confused:

ac3 extraction: right before your eyes: http://forum.doom9.org/showthread.php?s=&threadid=17787. as for the mp3.. you have to set it to full processing mode.. I guess you're doing DivX -> SVCD, and I just happen to have a guide on that, which explains you exactly how to deal with any MP3 soundtrack that's being used with DivX (that does not include ogg media streams but that's a different subject entirely because that has nothing to do with AVI anymore).

Thanks, I did actually read the guide first but virtual dub kept crashing when trying to do full processing.

I must have had something else wrong because after a rebbot it seems to be working fine.

I will be trying miniDVD next, so the extcartion of the ac3 track helps for the next step.

Is there a guide for DVD Maestro?
