I've got a problem playing dual layer bluerays, in PowerDVD they load but they just display a black screen and mediaplayer just sees an empty disc. I used to be able to play the standard edition of Avatar (which is a dual-layer disc) ok but it won't now play.
I've tried on two different computers niether will play either the standard or collectors edition of Avatar, on both computers there are no driver updates available for the blueray drive. Both computers are running Windows 7 (64bit). Both computers will play other bluerays as I tried a Battlestar Galactica blueray and it played fine on both computers.
The only thing that I can think of is that the Avatar bluerays might have some sort of DRM stuff on them which has gone wrong. Has anyone got any ideas?
