onkyo 805 and 7.1

[jabawonky]

just hooked up my brand new onkyo 805! never experienced high definition sound and it is amazing. Only problem i have experienced so far is not having my rear 2 speakers produce sound on 7.1 movies (such as shoot em up). I am playing movies on the ps3 and I have it set to linear pcm and i manually checked every audio option in sound options. When i look at the ps3 display it says DTS HD - MA and 7.1 is appearing. Any ideas?


Also I hear of people sound mixing so 5.1 movies or games play on all 7 speakers? not sure if I heard it right but would appreciate an explanation how to do so. I found the instruction booklet that came with the receiver to be very bland on how to do things.
