To figure out why things work as seen more details on each end need to be known, e.g. when set to Auto, what was the display seeing? Is it possible RGB was being sent and when the display sees RGB it interprets is at PC video levels as opposed to studio video levels. Is the Oppo somehow output PC levels? (I would hope you'd have to force it to do that).
When I first set up the Oppo I put it on 1080p but left the color space setting to 'auto'. I calibrated using both the S&M disk and the AVSHD disk, using the blue filters from the AVIA disk. SD-DVD quality was no better than my old player, so I tried 'deep color' at both 30 bits and 36 bits, running through the calibration each time. There was no change in the calibration, and no apparent difference in SD-DVD quality.
The next test was changing the color space. With a disk playing (Last of the Mohicans) I changed the color space from 'auto' to '4:2:2'. In both cases 'deep color' was turned off. The difference in quality was stunning.
I then tried 4:4:4 and the quality was still stunning. There is a marked improvement between 'auto' and the other two settings. It is a night-and-day difference, not some minor change due to calibration being off.
I then ran through the calibration settings, again using the S&M disk and the AVSHD disk. The calibration was spot-on, nothing changed.
I'm much happier with Oppo's SD-DVD quality. I may have something set incorrectly in the receiver or panel, but if I do it's a common mistake. Changing the color space to anything but 'auto' corrected it.
I suggest that jkozlow3 with his 106" screen try changing the color space setting. He might be able to watch an SD-DVD without zooming.
