vdub cutting a/v sync problem

[mategal]

I'm trying to make 2 svcds out of one avi file
the film 51'st state, 25 fps mpeg4, sound 48kHz stereo
Vdub doesnt like the movie it prompts : improper vbr, rewriting header => lots of skew....
The first svcd went ok. After that I tried to do the following:
open the whole movie, select the second part ( my second part ), save the waw, and the avi ( with audio ) . when playing back this new avi, the audio is out of sync ( by the ammount promted by vdub).
Aftre that I tried then to save only the video, than by addig the waw saving it as avi ( multiplex it ), the problem is stilll there.
the question to answer is : how to cut an avi in 2 parts ? ( while keeping the audio in sync) PLS help
I need to use vdub for frameserving cause I'm addig srt subtitles, and I have a working method in my hands to make my movies, and I dont want to mess up things ))
The above were inspired by faq, forum tips, but they didn't work out.

I have better luck cutting the movie during the encode process (with TMPGE).
First use Virtualdub to save the audio WAV.
Open>
"Movie".avi>
Audio>
Full processing mode>
Audio>
Conversion>
48000>
Audio>
Compression>
No compression PCM>
File>
Save WAV.


Then in TMPGE.
Set up your movie (and use the WAV you just made as the Audio Source).
Set up your template.
Setting>
Advanced>
Source Range>(double click)
Move slider to halfway point>
Click Set End Frame >
Ok>
OK>
set Output file name to..."Movie"-pt1>
File>
Save Project>
Save>
Setting>
Advanced>
Source range>(double click)
type in frame number in "start frame" box(copy from previous end frame box setting)>
Slide bar to end of movie>
Click on Set end frame>
ok>
Ok.>
Set output file name to..'movie"-pt2>
File>
Save project>
Save>
File>
Batch encode>
add (click on Pt1)>
Add (click on Pt2)>
Run
File>
Save project>

Thanks for the tip, I get what you are trying to explain, but I'm using cce, and only use tmpeg for the sound joining the later with bbmpeg, so this isn't a solution, but thanks anyway.
