I have had several problems with my BeoCenter 2 and while it is currently in for repair, I have attempted to set up my Playstation 3 as my dvd player.  I am using a Zector switch with my BS1.  Here is my problem--I am able to get the Playstation 3 games to play in 1080i resolution, but I have no picture when I attempt to play DVD's.  I get sound, but no picture.  Do I need a firmware upgrade on the BS1, or is there a way to change the settings on the Playstation 3 in its settings menu?
