A long while back I remember there was a thread mentioning that there is a problem with the white level on Sony's XBR400s, leading to a loss of detail, when recieving a progressive signal from a dvd player. In this somebody said that they had found a way to correct this problem by changing something in the service menu. Unfortunately I can't find this thread anymore. And since I own an XBR400 and I'm planning on buying a progressive player soon I'd really like to know how to fix this problem. Does anybody here remember what to do or even remember the thread I'm talking about?
