Virtual Dub audio sync problems

[onerag9]

Every time i try to join 2 AVI files together in Virtual Dub, the audio goes out of sync. When you play back the new file, the first half is perfectly in sync... but when it gets to the second half, as soon as it starts playing the data from the second file, the audio goes out of sync. I've tinkered and toyed with this for hours trying to find a solution, but with no luck. If anyone can help me out, it'd be appreciated.

There could be a slight difference between the two AVI's, in fact one of them might have bad frames.

Try loading them into Vdub 1.49 select video and audio streaming and save out another copy (Streaming takes a min or so). Do the same with part 2, then join the new ones together.
