Oh, lets add to that list; the many movies on the pay channels that aren't in oar. Some just weren't shot in widescree and some they just don't use the widescreen version / transfer.
Different HDTV signals?
When I tune into HDTV movie channels, the picture fills the entire screen on my 51" widescreen rptv. However, when I put on some of the HD major network channels, like CBS, NBC and Fox and some others, there are bars on the sides of the screen regardless of the picture setting. I'm using cable to receive the signal. Are there two (or more) different HDTV signals being broadcast?
