29fps avi to 25 fps mpeg2 problems!

[greig2000_uk]

I have been trying to convert my avi for burning to DVD which is:
Video - DivX3 fast motion Audio - mpeglayer3 (mp3)
aspect - 680x344 Bitrate - 112kb/s CBR
Bitrate - 711kb/s sample rate - 44Khz
FPS - 29.970
Whatever I do I cant get the audio and video in sync!
Iv tried extracting the audio with virtual dub (saved as mp3) and running it through besweet (output to 48khz wav) with no joy.
also tried using avifrate to change fps to 25 and using V/D and besweet as above, this adds 29 mins to the film length and it plays to slow!
Also various other methods with the mentioned software with no joy.
I want to use V/D as a frameserver to TMP as TMP is crap at framesering so if anyone can give me some details on how to convert this kind of file using this method or even if you know a better method it would be very much appreciated.
cheers.

Has anyone ever done this conversion before? Or is it a major problem?

try opening the original divx with virtualdub, saving the sound as uncompressed wave then opening the wave, -audio - wave audio, check whether the sound syncs throughout, by watching various bits of the movie, now save it as avi - video direct stream copy, audio wave audio. Now use this as input to TMP, usually works for me........ the only sync probs you will get with this is if there is corrupt video frames in the movie (which always cause sync probs & r a real pain)
