Hi guys, I'm confused about this (as well as many other things)! When using Multi channel analog inputs on a 3.1 system from Samsung BD C6500 to an old Onkyo R520 will I be able to receive all surround channels through just the fronts, center and a subwoofer by setting surrounds to none in the BD player? Or am I better off using the Optical connection (the Samsung has no other options except HDMI which the Onkyo dosent have) and letting the receiver process the PCM to some type of surround?
