I recently got a plasma display, and the aspect thing surely is a pain. My remote has a little red button to change aspect, and I expect it will wear out long before the plasma dies.
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?
