VDub .avi "fixing"

[roughbuddha]

ok, so i have these .avis that i want to encode to put on DVD (I use TMPGEnc to encode them). TMPGEnc says that i cant make them less than 24% of the disc, and i run into this problem all the time, so all i do is put the file in VDub, do a direct stream copy of the .avi, and then try to encode it again and it works fine and i can make it an acceptable % of the disc. But on these .avis, the sound gets desynched with the video. How do i fix this?

I'm using VirtualDubMod 1.5.10.1

The message when i open the .avi -

VirtualDub has detected an improper VBR audio encoding in the source AVI file (audio stream 1). The current preference is to rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 5277 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder.

Save the audio to a wave file, the use both the video and audio files with TMPGEnc.
