Any ideas on the best setup for my new system? I just bought a Blu Ray player to go into my Onkyo surround sound receiver. My receiver doesn't have HDMI ins. It does have optical in, coax digital in, and analog 7.1 inputs. The Blu Ray has outs to match all of those. If the analog ins and outs are the way to go, does it matter what type of cable to connect? Copmposite cables, component cables? Does it matter since they're just carrying audio?
