I have a Dell Dimension 4600. When I burn an AVI file and play it back, there is some missing audio and jumping video that occurs. I have burned DVD videos with no problems. What could be wrong here? Thank you. Andy

Maybe you can check on this article "Why There is No Sound after Burning DVD" which offers some solutions for no sound issue after burning DVD.

Basically, the reasons can be as the following:

1. The audio in the original digital video to be burned to the DVD disc is out of order.
2. Audio and video filters.
3. System codec missing.
4. The operating system drive is out of date.
5. DVD disc incompatibility. If you are inserting the DVD discs to a disc drive which is not compatible with.

1st convert AVI files to MPEG2, use a good converter....

just
add the AVI file in Nero(Vision...make movie option/ Export option / Configure option...) and let it convert to MPEG2 first....
