I recently set up a htpc to use with my Nec vt540 projector. I am using windvd and powerdvd. When displaying the Windows xp desktop I have the projector set up to perfectly cover my entire 120 inch 4x3 screen. A problem I am having is that when I play dvds in full screen mode many of them don't stretch horizontally all the way across the screen. Some dvds have a black border on the left, some on the right and some on both. Some dvds fit perfectly. Vertically they all fit perfectly.(4x3 material of course) This situation is the same with windvd and powerdvd. When I use a stand alone dvd player all dvds fit perfectly with no borders. Is there a solution to this problem ?
