Hello everyone, I just recently watched Dark Knight on bluray. I noticed when a scene came up that was filmed in IMAX it filled my 50G10's entire screen but the rest of the film had the usual black bars above and below. My question is why can't the hole film stay in full screen, I'm not a complete moron but I don't know as much as many of you on this forum do. Do they crop the films or is this just the way the original looks. I am also a bit crazy about anime as well, and i own Apple Seed EX Machina on bluray, that entire film fills the screen and it has nothing to do with my ps3 or tv settings they are set to view whatever the incoming source is inputting. I know that the Eric Banna incredible hulk widescreen dvd is like this as well, again if some scene's or some entire movies can still be widescreen yet fill the entire screen why can't they all. Any input would be greatly appreciated, oh and sorry about the spelling I know it's pretty bad.
