There are two HDMI output choices under the Blue Ray settings for my PS3: Bitstream or Linear PCM
After playing around with the two settings and the two audio tracks on the Spiderman 3 Blue ray , this what I get on the display (TV) when I press select on the controller when the disc is playing.
Bitstream
TRU-HD track- DD Multi 48khz, 640kbps
Uncompressed 5.1 track - Linear PCM 5.1 48khz 4.6 mbps AVC fluctuates from 20-30mbps
PCM
TRU-HD track - DOLBY TRUE HD 5.1 - 48khz , fluctuates 2.8 to 3.5 mbps AVC 23-26 mbps
Uncompressed 5.1 track - same as bitstream above (uncompressed )
All four combinations sound good to me but I was wondering what the numbers mean and which do you recommend. Notice that the TRU-HD displays only under the PCM setting and also note that the reciever icon for TRU-HD (DA5300ES) does NOT come up on any of the settings.
