I have a similar problem. I have Nr1602 connected with optical cable to viera gt50 series plasma and energy take classic speakrers set. Purchased it few days back, so I have yet to buy another HDMI for TV - receiver connection (only one at moment connects TV and set top box) and ethernet switch to connect marantz on home network.
Now, i have downloaded some 5.1 FLAC files - classical music, put it on USB stick, connected stick to TV and tried to play it. Marantz recognized it as plain stereo. OK, maybe TV isn't set up properly, so I tried to play it from USB port on Marantz itself - it's a little bit pain in the a** when you don't have a display on TV to navigate through stick, but OK.
Marantz refused to play files. All four of them. Goes from one to another, starts playing just one but just for few seconds with interrupts and problems, then locks. OK, maybe I need a firmware update - files are OK, PC and TV have no problem playing them.
So i downloaded another 5.1 FLAC, this time Pink Floyd's dark side of the moon (good thing for checking surronud... ) and this one plays from USB directly on receiver no problems, but... marantz still recognizes it as stereo, and i found no way to make it play 5.1...
So, what went wrong?
