hi, having a right hard time trying to work this one out for some reason.

i have several movies burnt onto a bluray disc, they work perfect in my bluray player and my imac but for some reason they wont play any audio on the ps3, the video is fine but no audio.

the weirdest thing is though if i copy any of the films from the disc onto a usb stick they work perfect in the ps3 even though it is the same file ?

i also have some that wont even be recognised by the ps3, but showtime see them but wont play them, same thing copy them to a usb pen they work fine, tried 3 ps3's and they all do the same ?

got me beat.
