need help with pcm uncompressed wav

[litlin]

I used virtual dub to extract my video from an xvid avi file so I can backup onto dvd-r. When I opened the avi, vdub said my best bet was to convert the audio to uncompressed pcm wav then decode using a contant bit rater decoder or something like that, because headers were messed up.

I am not sure what to do?

I have my m2v file ready to author dvd-r (did this in cce), but I am not sure how to get the sound out of the original avi and have it be in synch.

Thanks in advance.
