If the player is doing the decoding, you just need to make sure the receiver can accept multichannel linear PCM over HDMI if you're going with a digital connection, or that the player has multichannel analog outputs and the receiver has the multichannel inputs. None of my players even have the ability to send the new sound formats out as a bitstream, but perhaps firmware updates will allow it. I'm still foggy on some of the specifics, but maybe this helps a little.
