Have it connected analog to an Onkyo HT-R530 and get everything but center on a brand new Panny BDP55. Doublechecked everything and simply ran 6 coax from dvd to receiver surround inputs. Sound is great on DVD stereo setting but no center channel. I do get center channel if I switch to MULTI CHANNEL setting on receiver versus DVD. Help. Is my Blue Ray broken or is it something esle.
