Liz, Now I understand what the problem is. You chose the data format when burning your DVD. The data format is designed for using a DVD on a computer. It won't work on a regular DVD player that is not connected to a computer. You need to choose the audio format when burning a DVD that will be used on a standard DVD player. I hope this helps.

I converted the avi file to mpeg-4 (which turned out to be mp4) with replay converter then burned it on to the DVD using nero express version 6. The only choices I got when choosing to burn the DVD were audio and data so I choose data. Am I missing something here? How about wmv files would that conversion be worth a try? Thanks. Liz
