Great question that I also need the answer too. Just saw a guy post that is looking to buy a Sony HTIB with 2 HDMI inputs and 1 out. That would solve the problem. The other problem is that I do not think you can run HDMI and digital coax from your cable thus if you run HDMI from cable to TV you have to somehow get the sound back to the receiver. Unless you have digital out on our TV then you must us the AV out...you loose the digital sound..I think.
