I have a 65" Sony Widescreen Projection HDTV. I have Comcast digital cable, and I have the HDTV Cable box hooked up using component cables. Whenever I am watching a program in HDTV, such as the Florida State-Florida game that's on ESPNHD right now, it's always in letterbox format. Is it something I am doing wrong with my setup? Is this normal? Could it be my TV? I would think that when watching a program in HD, it would fill up the entire screen. I have 4 screen modes on my tv, regular, full, zoom, and wide zoom. My TV automatically selects the screen mode for whatever the input is. Such as for dvd's, it goes into full mode and the 16:9 movies fill up the entire screen, along with my widescreen xbox games. And it automatically selects normal for HDTV programs which are in letterbox. The only way I can get my HDTV programs to fill the screen is if I select Zoom, and well, that just looks like crap. I'm not really educated on this type of stuff, so any knowledge you could drop on me would be greatly appreciated.
