I just picked up the Sony at Tweeter today. I put in Black Hawk Down Superbit, and the image quality is awesome on my JVC PD42WX84. Hooked it up using a Monster HDMI-DVI adapter and a DVI cable. There is definitely an improvement at 1080i over 720p. I did not notice any green depression, but I'm also slightly red/green color blind, so who knows. . .
The problem is, after about 30 mins, I got the "Tray Locked" sign on the display and the tray would not open. I tried unplugging for 10 min and trying again, but no dice. I took it back to Tweeter and they gave me a new unit, but my disc was still stuck in the old one. They took a screwdriver and just opened the thing up right there on the counter and after a bit of trouble, got the disk out. To get it out, they had to unscrew the entire transport and unplug a litany of internal cables/ribbons. Long story short, it was a pain to get the disk out, and I wouldn't want to do it at home. The guy looked like he was having a hard time getting it all back together, and even then, the tray is still likely to be locked. It seems like this may be a problem with some of these Sony units, although the Tweeter guys said they had not seen it before. Hopefully this new unit will be trouble free.
One other thing I noted is that I suspect there is some type of HDCP handshake issue. If I turn off the DVD player while the TV is on, and I keep the TV on, the DVD player will not power up again. I have to turn the TV off for the DVD player to power up, so it appears I will always have to turn on the DVD player first. A minor annoyance, but certainly not a dealbreaker. Maybe it has to do with the adapter I'm using?
Bottom line - I threw in Black Hawk Down superbit, Spidey 2 superbit, LOTR - Two Towers, and Harry Potter, and they all looked great. I didn't notice any ICP or CUE, and at least for me, I don't notice any green depression. I took the advice here and set the Hue and Color down, and also adjusted the picture and brightness to get BTB. I'm gonna use Avia tomorrow and play around with it some more.
