I recently found out out how to make backups of some avi files that i have on my computer. I have been able to convert them to mpeg and then get the vob files. I proceed to burn the dvds using nero. My problem is when i go to watch the dvds on a stand alone player, the video is very choppy like the disc is scratched. I’ve tried burning at 2x (which is the slowest speed nero will allow), and it continues to do the same thing. If i play the dvds on my computer using power dvd (in my dvd burner drive or my dvd player drive), they play just fine. I also just checked the mpeg file on my hardrive and it plays fine too. Is there something im overlooking to get perfect playback on all machines?
