Have tried to rip this bluray with every release since BD+ has been added to fab up to and includng 188.8.131.52 release, but it always results in the same thing, I can get the picture but no audio.
The Disc is region B and uses Dolby True HD Audio.
I don't burn anything, only play from server streamed via PCH. Also try playing file with PS3 and it's the same result
I think this has some protection that is getting left behind to stop audio output.
