I have a Ripped DVD, someone else ripped, Plays on one of my DVD players but won't play on a newest acquired DVD player, Samsung HT-X50. When I try to play the DVD, the player says "Playback Prohibited" I found an obscure line in the Users Manual that it doesn't play pirated dvds! How can it tell? Should I try to re-rip the DVD? Or just forget about it?
