Interestingly, I recently tested this on my 650. My Dad has a Sony 40EX400 and Dish Hopper. The Hopper had issues with sound dropping out via optical, so as a workaround till they could get a software fix, we piped the HDMI to his Sony, then optical to the receiver. I would have lost a very large sum of money on this, but he was getting 5.1 DD from the Hopper through his TV. I tried this on my 650 (I also have a Hopper). It worked on the first channel (after swapping from my receiver), but any channel after that it didn't. I have a feeling that the hardware is there to pass 5.1DD, it's just the TV tells connected devices it only handles 2.0 audio, so that's all that the source sends. It'd be interesting to pop one of those HDMI EDID boxes in the chain, to tell source devices to send DD5.1, I have a hunch it'd work.
