Is there any video format guaranteed to play on a stand alone DVD player? I've already wasted 3 DVD-Rs trying to burn my videos. They were originally .avi, but I converted them to .mpg (mpeg-1 I think...) and proceeded to burn them to my DVD-R. They won't play though. If I convert them to mpeg-2, will they most likely play? Do I have to do anything else besides convert the files? I already asked a similar question, but I'm still confused and don't want to waste anymore discs.
