Thanks for the suggestions. I have been working with Oppo on this as well. I did not have this problem when using the 970 with a projector...there's something odd with my television. I tried my Denon 1730 with it as well and have the same problem if I set the black level to "on" (which I'm guessing is a blacker-than-black switch of some sort). It calibrates fine with black turned "off" (which is the default on the Denon) so I'm just gonna use it with that TV and save the 970 for my next projector.
