This is borderline what we can't talk about seeing as you didn't say what the movies were. Soo, I'll just say the format is very specfic. You can't just burn any random video to a DVD and expect it to play on any DVD-Player. Computers are usualy more forgiving than DVD players too, when the settings aren't quite to the standards. Finally, I've found a few DVD-Players that just plain wouldn't read burnt DVDs. Usally, the cheaper it is, the better it reads burnt disks.
