My receiver has just about everything I need I hope (sherwood newcastle R-772) Cool I didnt waste my money on the monster SACD 5.1 direct input audio cables. So let me get this straight I hook the oppo with both HDMI and the 5.1 RCAs into my receiver? Next my comcast cable box has HDMI output and optical and component so would I also connect the cable HDMI into my AV reciever? I had someone say use the optical on the cable box so optical or HDMI?
