OK, I have my Panasonic RP91 connected to my Denon AVR-3200 via the six analog outs. I've set up the RP91 for small speakers (NHT SuperOnes L/R, SuperCenter, SuperZeroes as surround, Mirage sub). Question: I've already adjusted speaker delay times in my Denon. Do I need to do it in the RP91's setup screen too? My feeling is no, but I just want to confirm. Problem: In order to check what was going on with my sub (see below), I tried to play an old favorite CD, a Telarc Michael Murray organ CD. It refused to play. Tried another old, off-market organ CD. Refused to play. Other, newer CDs, played fine. The CDs are fine (no fingerprints or scratches to speak of). Does anyone else have problems playing CDs with their RP91. Bonus problem: I was trying to check what was going on with my sub due to what I've found with one of two DVD-Audio discs I have, Bach: Organ Spectacular (Ton Koopman). I'm getting absolutely ZERO output from my sub with this disc, regardless of settings in the RP91. I am getting sub output with the other DVD-A disc (Bela Fleck), so it's not the sub. Anyone have this disc too by any chance? Can they confirm what I'm (not) hearing? Thanks in advance.
