I'm late posting due to vacationing from EVERYTHING over the holidays but if it is still relevant, I do have a Denon 3806.

I am running video and audio from my Toshiba A2 over HDMI to the 3806. No problems.

I am running video only on HDMI from my Bell ExpressVu HD reciever to my 3806. Audio is optical. No problems.

From there it switches video to the HDMI Out to my TV, via a HDMI to DVI conversion cable. No problems here either.

With great power comes Awesome irresponsibility.
