My brother and I recently both purchased the Panasonic RP56 progressive player. When hooked up to my brothers XBR400 the picture is so bright in progressive mode that he has to turn his brightness level all the way down to zero. I have the Sony 53HS10 and have no such problem. We tried hooking his player up to my TV and everything was fine, so there is some kind of issues with the XBR400. Just wondering if anyone else has the RP56 hooked up to an XBR400 and if they are having similar problems? Tim.
