BD title production (NIN)

[Greenmatiz2]

One more thing... why am I not getting my rear channels out of this title: I can't get any rear speakers in either TrueHD or Dolby Digital. My 5 year-old Onkyo receiver can read the optical output, and should be getting full 5.1 out of it, at least, right?

I'm only getting the front 3 speakers (happens on the audio set-up as well).

My PS3 appears to be set up properly, as well.
