I haven't set up my Yamaha Aventage RX-A870 AVR yet. I was trying to educate myself about the plethora of HDMI inputs on the back of these newer AVR's. I still question if using these are such a good idea. I'm not sold on running everything through the receiver. I view it as another source that the signal has to pass through. I'd still prefer a direct link from my DVD or game system to the TV and just using the optical out from the TV to the receiver. Is my logic outdated or should I not consider it? If I ran my DVD player directly to my TV and ran audio out from the TV to my receiver, would the receiver still be able to decode and decipher the surround format?
