Sounds like you did good so far.

The sub issues sound wierd. Just to get the most obvious possibility out of the way, you're using a digital connection between player and receiver, not stereo audio right ? Sorry to even ask this but the first thing that popped into my mind was "he's running stereo and the receiver is doing a pretty fair job of regenerating the channels"
