AvFan: You're calibration settings do seem a little odd just looking at them. However, if that's what the meter is telling you, then I guess they're good. You may want to try the test tones off a THX DVD (such as Star Wars) if just for comparison sake.

As for the Oppo, I'm not an owner but I was wondering about the "downmix" setting. After reading the manual, I would set it to "7.1" Why? Well, it seems to me that that's the only setting where the player isn't doing anything to what's on the disc. Are all of your speakers set to "large" in the Oppo? Same reasoning for that question as above...
