I just bought the Samsung BD-P2550 and have about 13 Blu-Ray titles and sets to have fun with. When I went to play the Alien vs. Predator / Aliens vs. Predator Requiem box set the first title played fine but Aliens vs. Predator Requiem made a popup come up that said 'This disc is not playable'. Now as soon as I hooked my player up I updated the firmware to the latest as of yesterday (3/7/2009). So I don't actually know if it would have played on the original firmware or not. Can anybody confirm this combination of player, latest firmware and Blu-Ray title? And if so can you provide a list of your settings if it does work? I do know that this Blu-Ray has a unique menu system and I can say that it does work on a PS3 as I have tested it on my friends and it played fine. Thanks for any help you can give in advance...
