I played more than a few BR movies and they often have 2 black bars at the top and bottom. It seems the 16x9 isn't enough to hold those films. If you want to know more, read http://hometheater.about.com/od/televisionbasics/a/aahdtvfaqs6a.htm
I have samsung LN40B530. I bought samsung bluray BD 6500. I played 300 movie today and I am getting black bars at top and bottom. I was having same issue with my old DVD player, I thought bluray would fix the issue .
I tried to adjust aspect ratio to 16:9 wide, it didnt help. 16:9 normal didnt help too.
I called samsung 1800 number. They said it is the way bluray disk is behaving, other disks might work fine for you, we can't do much in this case.
Any one has the same issue and has any suggestion for me?
