Graeme, I want to help, but I think you need someone smarter than I.

What I meant was "will the blu-ray player do the decoding for Dolby True HD or DTS-HD and then pass the decoded signal to the receiver via optical or analog cable?"

It appears (from page 35 of the manual) that the player will pass Dolby TrueHD via PCM to your receiver through HDMI 1.1, 1.2 or optical. It doesn't seem to decode DTS so it's not a complete solution, but it is "something".
