I haven't set up the receiver yet, wont be doing that till the weekend. Just opened it up to read the manual and it says:
Audio Mode: Left, Right, Stereo
SPDIF: Set to Bitstream, Mute, PCM

This is bugging me as from my understanding;
Bitstream - will send the raw digital audio without processing out of the receiver to the Amplifier to process/convert.
PCM - the player will convert all audio and output as 2 channel PCM.

Or have I got this wrong? why isn't it Linear Multi Chanel PCM etc?

So to my question, does this receiver definitely output 5.1 from the Digital Coax 1xRCA? As i definitely require 5.1 output. Do any of you know the answer, have you tried it?
If the receiver sends raw Multi channel digital audio through the digital coax, then it's upto the Amplifier to decode it on the fly. If this is the case then my Amp will only accept DD/DTS/AC3 as it cannot decode AAC.
Do any channels even broadcast in AC3? or is it all AAC?

Also how come the USB port is at the back, i'm sure most Eagle HD800 (non Mini) are at the front under the flap with the Card slot.

Please reply thanx.
