I have recently upgraded my Beosystem 1 with a newer Beovision 4 plasma that is 1080p but without the built in camera.  The software is the most current version 4.7M.  The Direct TV box is connected to the Beosystem 1 with component cables directly, no Zector box.  If the HR 21 is set to 1080i the pictures is so dark it is unwatchable.  If I set the HR 21 to 480p the picture is not dark and watchable but not as sharp on HD channel as the 1080i.  Anyone else encountered this problem?  Any solutions besides the standard B&O answer of upgrade to a Beosystem 3.
