I was thinking that some TVs' strength is their Component Video section, while other TVs' strength is their HDMI section. So I guess when I need a 32" to 37" TV for my livingroom, I'll have to take my BDP-320 to the store and set the TV's backlighting and video adjustments to my liking and pick the TV that looks the best.
I'm going to guess that it has something to do with your TV and not the 320.
I had my TV, a Pioneer Elite plasma, professionally calibrated by a highly regarded calibrator (D-Nice on the AVS Forum; he's considered quite the Pioneer guru). At the time I was using a Pioneer BDP 51 player. In terms of PQ, the 51 is indentical to the 320 (at least via HDMI). The only PQ adjustment required in the player was to lower White Level down 1 click due to a known issue with some Pioneer plasma/Pioneer BD player combos crushing whiter-than-white signals.
When I replaced my 51 with the 320, I contacted D-Nice to see how this would affect my calibration. He said that the 320's picture performance was identical to the 51 and to just lower white level just as was done on the 51.
So it would appear that there is no issue like you described with the Pioneer BD players, hence my guess that it is your TV causing the issue. Perhaps the factory calibration on your component inputs is better than your HDMI inputs and the user controls don't allow you to correct this (it may require service menu level adjustments which you cannot access).
Hope this helps.
PS - To those who responded by just criticizing the poster's TV, that was unecessary, is no help to anyone, and is not the purpose of this forum.
