For the record, my television is calibrated to the best of my ability, and I think that if it wasn't then ALL of my HD channels would look like DIVX 3.11 encoded video in 16-bit color depth. I guess I owe NBC WVIT-HD an apology (not like it was LOOKING for one) for declaring it the worst local HD in CT. While it still has numerous issues with macroblocking and fast motion, at least it still looks good during typical television viewing (ie NOT sports.) I've had HD programming for a few years, but only recently upgraded from a 30" not greatly calibrated Samsung CRT HD to a 50" Panasonic Plasma with what I consider to be accurate picture adjustments. I guess it's only now with a clearer picture can I see how horrible things can be.Sounds like your TV is not calibrated correctly, you are sitting too close to it, or both.
Your brightness is obviously off if your bar theory holds true. The contrast is probably 100 as well as the sharpness. I'm not saying this is you but most people's TVs are this way because that's the default settings and people don't know any better.
