I received my 52" XBR4 today. I'd like to thank everybody in this thread who really helped me greatly speed up my setup time. All went well (no clouding, dead pixels, etc.), except I have some sort of HDCP issue (I think) with my Motorola DTC-6412 STB. I can only get a picture over HDMI (using Monoprice DVI->HDMI cable) for anywhere from 5 seconds to about an hour, then my screen goes black (or at least a VERY dark gray
Anyways, I guess I can just use component 'til I get this straightened out...to my eyes component looks quite good on this set, it's just that I was looking forward to going all HDMI (HDMI on Sony upconverting DVD plays no problem).
One other thing...I've already become a bit addicted to watching movies (or at least parts of movies) with Motionflow set to high. I watched part of The Fifth Element tonight, and it was freaking me out, looking at Bruce Willis walking around in what looked like the set of a soap opera.
