Hi, having moved over from HDdvd to bluray, (my bro lent me his ps3 til i buy a proper player), i am struggling to get anything other than dolbly digital 5.1 at 640kbps out of my amp. I had this superb film on hdvd- better front end by the way, and it was in tru hd. i can get the ps3 to decode dtsma and ddtruehd and send it via linear pcm to my onkyo605,(bitstream is the one for proper players i know), but the sound on this film is only 640kbps plain old dd. Have i a funny copy ? It only says dolby digital on the box too, but reviews on here and hi def digest suggest true hd or dts ma. Please help i won't watch it til i can get better sound.
