Not sure if this is the right place to post this.

I had a problem with an AVI that had dual audio.
Track 1 was in Spanish
Track 2 was in English
Could play the english track In VLC or Media Player Classic
by switching aud to track 2.

Could not burn the avi to disk and have it play the English track

Got a copy of VirtualDubMod which will let you swap tracks or disable 1 and re-encodes the video.
When doing the re-encode make sure it is set in uncompressed mode else it takes up a ton of HD space.

It also corrected a slight out of sync problem.

Think this is something that would be a great help to everyone if the shold have problems with an AVI.

Thanks for the tips. I will give it a try.

Try the free Solveig AVI Editor:

Drag the AVI into the editor. Choose the soundtrack that you want to use within the checkbox. Click on Invert then Run. In less than 2 minutes [for a 1 hour AVI] you'll have the AVI that you want. This puppy is very fast!
