I have a Dell XPS 410 running PowerDVD 7.1 and everything works just fine there for playback. I have a Mac Mini running Boot Camp in the Master bedroom running PowerDVD 6.5. You can't get PowerDVD 7.0 or higher to run on the Mac Mini as it fails the graphics card test or I would obviously be running that. With that said I have a growing list of movies that just won't play in PDVD6.5. They start to play for a second and then quit instantly. If you try and open the .EVO file by itself, same problem. Is this a difference in encoding? Anybody have any ideas here? Could it be something in the XPL file? Its just too weird. HD-DVD's that will not play in PowerDVD 6.5 V for Vendetta March of the Penguins Charlie and the Choclate Factory Forbidden Planet A Scanner Darkly The Departed The Lake House HD-DVD's that work in PowerDVD 6.5 Ant Bully Van Helsing Fast & Furious Tokyo Drift Brokeback Mountain 12 Monkeys Apollo 13 Casino Children of Men Chronicles of Riddick King Kong Lucky # Slevin Phantom of the Opera Pitch Black Serenity Space Cowboys The Mummy The Thing Troy Waterworld Any help here would be much appreciated!
