I Burned a movie on my Optorite DVD Burner using Princo DVD-r 1-4x media & tryed to play it on three different computers. First computer with a Pioneer DVD-115 Rom the movie played fine. But other two computers both with Pioneer DVD-120 Rom Drives lock up and will not start movie at all. Anyone have any ideas why. Is it media compatability. Should I try different brand. movie also plays well on my standalone DVD player.
