Strange audio sync problem

[legionpc]

I have an avi which is too long to be encoded to SVCD in 1 part, so I split it into 2 parts in vdub. Audio was saved seperately as uncompressed wav, video was direct stream copy. The first half I ran through tmpgenc, it encoded fine, works great. The second half the audio is severely out of sync, like it plays 3-5 seconds before the video, and I have no idea why.

I mean, the audio begins at the same time as the video, and as the audio was perfectly in sync 1 frame before (the final frame of the first part) so how can it be so out of sync immediately in part 2? I tried cutting it again, resaving the audio, same problem. Why is this happening?

open the part2.avi file in virtualdub
go to audio/interleaving
there's a 'delay audio track' option
if you hear an event before you see it, the delay is positive
if you see it before you hear it, the delay is negative
the value is in 'ms'...
try it... you'll find out the perfect value to put there after 2 or 3 times

But after cutting the audio and video aren't in 1 file. Original file is say movie.avi, then after cutting i have: movie-part1.avi, movie-part1.wav(that encodes a perfectly synced svcd) and movie-part2.avi and movie-part2.wav (and those encode an out of sync file)

so opening the avi in vdub doesnt have any audio anyway

open the avi file in virtualdub
go to audio
select wav audio
open the wav file
and do as in the first reply

Found out why I have the problem - after cutting, part 2 of the audio is 46:18 and the video is 46:29... How on earth does this happen? I cut them both on the exact same frame

And as for introducing an audio delay as you mentioned, I'd prefer not. There should be a way to fix it without doing that
