I have a german DVD which is PAL and made a backup of it and burned it to a DVD-R since the original DVD is in state of no return. Now the DVD of course I know will not work in NTSC televisions but when I play it in my laptop/PC/Xbox 360 it plays fine with no error nor warning messages. When I play it on my Panasonic dvd player it plays fine aswell but there is horizontal screen flipping, and when I use it on my sanyo DVD player it just says Error (Which I totally expected) But why does it work on my Xbox 360? It's connected to a NTSC television set aswell. Is there any way to make it work on the panasonic one? I've been looking into converting to NTSC but it's too much a hassle and I want to keep original languages and subtitles and 6ch audio.
