I've had a few days to play with the XBR450. It replaced an XBR250. Some quick impressions: Very good out of the box. Service menu tweaking included turning off the red push, decreasing overscan [which was not too bad to begin with], centering the picture, and a slight geometry adjustment to the lower corners. I probably could have done more, but decided to quit while I was ahead Letterbox bars look just about perfect. If I look REALLY hard, I can sometimes see a very slight bulge in the lower bar. I did not need to adjust the tilt. The NTSC standard setting does seem VERY "red",which is how its supposed to look. The XBR250 NTSC setting was not this red. However,it is very difficult to get used to. I'm giving it a chance,but may return to the "neutral" setting which looks great. I know, that's a heretical statement! Video from a TiVo looks better than I've seen on previous sets. DVD's of course look tremendous. I do not see any real obvious improvements when the DRC is set to "Cinemotion" [Sony's 3:2 pull down mode] as opposed to its regular interlaced mode. Audio from the built in speakers is a bit better than in many TV's. I don't know what the designers were thinking when they came up with the stand for the 450. Let's just say it looks "interesting"! I found a great TechCraft stand that will hold a 36" set up to 240 pounds. The stand's best feature is a space for a large center channel directly under the TV. Perfect for my situation. Questions?
