Recently, I've being having a few problems burning .avi files to DVD. I'm currently using Nero 7 ultra edition to convert and burn the files. The resulting DVD's play fine for the first 50 - 60 minutes and then begin to skip or stop altogether. I've tried converting the files using WinAvi but when I tried to burn them using Nero I got an error message. Has anyone else had similar problems or can offer some guidance? Many thanks.
