I recently purchased a Panasonic xp-50, and while viewing a 480p image on my panasonic 47wx51, I must reduce the brightness setting on the TV. Once I do this, the image looks great, but I am wondering whether others regularly have to make these types of adjustments when viewing progressive scan materials? Or is there something wrong with the player? For what its worth, the 480i image seems to "match" (in terms of brightness setting) the regular cable TV images that I watch for the majority of the time. Thanks for any insight into this situation.
