I also have an Onkyo 602, and what I do, is run the video right to the TV instead of going thru the receiver and maybe compromising the signal with a few extra connections and circuitry. The audio, however, is run thru the receiver: The analog and digital audio "out" from the TV goes to the receiver(as the cable co-ax, analog audio and component video goes directly to the TV)so the receiver gets cable signals from the TV instead of the cable box.

Oh, and I do the same with the DVD and games: Video to the TV; audio to the receiver!

Works for me, anyway!
