I have the Oppo connected via the supplied HDMI cable to a Denon 2309, and from there to the Panasonic 600u panel using a new Monoprice HDMI cable.
The Denon's input is set to not do any video processing on the HDMI input.
The Oppo is set to bitstream the audio, and the output resolution is set to 1080p (not auto).
The TV reports 1080p input. Originally the Oppo's color space was set to 'auto'. I connected the old DVD player via component to an extra input on the TV. I put in two copies of the same DVD (LOTR:FOTR) and compared the two players by swapping inputs on the TV. I really did not see a difference.
I even put the Oppo into 'demo' mode and compared the left & right sides. I saw very little difference, and slightly prefered the un-processed side.
When I forced the color space (remember it was set to 'auto') it was like the ABT chip woke up. There was a striking difference in quality. I can switch back and forth between 4:4:4 and 4:2:2 and the excellent quality is still present. It was only in the original 'auto' setting that something was missing. It was almost like the Oppo was set to 'Source Direct', although I know it was set to 1080p.
I have not gone back to 'auto' so I do not know if it's a problem with the HDMI handshake or just a one-time setup problem.
I have gotten PM from someone who saw the same improvement in quality by explicitly setting the color space.
If the Oppo's SD-DVD upconversion is not what you expect, try setting the color space.
