Thanks for the help solving this issue and verifying my manual calibration settings make some sense. I thought of the OPPO as the possible problem, but the trim levels in the OPPO are set to 0, delay is set to 12 feet for all channels and downmix is set to 5.1 channels. The OPPO delay settings are not correct but I can't imagine it would be the cause and I'm not sure I want to induce double delay settings; I'll let the 990 handle that chore. Strange!
