ok just tested a few movies to see exactly what i'm getting, and the display shows as such-

3:10 to Yuma offers 7.1 PCM audio, and DD Surround EX-

when i opt for 7.1 PCM - my reciever displays PCM, and the PS3 displays Linear PCM, 48khz (this # is the same for every codec), 6.1 mbps

when i opt for DD EX - my reciever displays Digital, PS3 displays DD Multi Channel, 640 kbps

Sunshine offers DTS HD Master Audio, and DD 5.1-

when i opt for DTS HD MA - avr displays DTS, PS3 disp DTS, 1.5 mbps

DD 5.1 - same as DD EX, but at 448 kbps

Spiderman offers Dolby True HD 5.1, and PCM 5.1 Uncompressed-

Dolby True HD - same as DD 5.1 above.

PCM 5.1 Uncomp - AVR disp PCM, PS3 disp Linear PCM, 4.6 mbps



on every title the DD codec sounds inferior IMO.
