Top Upconverting Blu Ray Player 2009 Why Do Blu-Ray Discs Mostly Come In Widescreen? I Hate The Black Bars!?

Why do Blu-Ray discs mostly come in widescreen? I hate the black bars!? - top upconverting blu ray player 2009

I have a PS3 and I have a 1080p HDTV, and I was very disappointed when I last night, a Blu-ray looked at him and he had black bars top and bottom of the screen as time. I was told by many that if you have an HDTV and watch a movie fullscreen, no black bars. There is no way to get rid of black bars, while you? I was really excited but at the same time, I mean for watching TV potential FUL Blue-ray DVD instead not to go to 1080 P. Do you know whether the publication of the Blu-ray view in full screen or the little screen later? I know there are some that are not large, but most of them. I also have an upscaling DVD player, but does not transmit in 1080p, and I ask myself, why not? Why Blu-ray is the only thing that should be completed in 1080? Thank you for any help!
