I've managed to burn my first project successfully to DVD and it plays back as it should. When I burn the exact same project to Blu-Ray (TDK BD-R 4X 25GB) MEP reports that the burn was successful as does Windows 7. When I attempt to play back the disk on the computer it won't playback, VLC reports an error as does Power DVD. When I attempt to play it on my Samsung BD Player, the disk starts and loads up the disk menu, when I click play, it simply returns to the menu. If I go to Scene selection and select a scene, it simply plays the main menu again. I've checked the content of the disk and the main movie is there in the correct format for Blu-Ray.
I've done this twice now and both times it had produced the same results
TIA
