I've just set up my Pioneer VSX49TXi receiver with M60's, VP150, and QS8's. The receiver manual says to connect both analog RCA's and digital coax from the DVD player to the receiver, so that I can still play DVD's that don't have digital surround encoding. When I connected both and played Star Wars Episode I, it only would play in Dolby ProLogic II. When I disconnected the RCA's for audio, then it played in Dolby 5.1.

Is there a way to connect both and prioritize which output is played?
