There is a way to undo linear stretch-o-vision by changing your HDTV settings. On my 2 displays, changing the HDTV setup to 480p shrinks a 16:9 image down to 4:3. I don't like using it, but do use it occasionally to watch a stretch-o-vision program. You have to change it back to your previous setting (720p or 1080i) to properly display true HD channels.
Really? I thought that just cropped the edges off just like the greybar function with the zoom remote. It could be the way your displays work. My Mitsubishi will unstretch/zoom/stretch 480i/p but will only stretch 720p/1080i. My Westinghouse will only stretch.
Might do the job but keep in mind at 480 you are not watching HD anymore.
He/She wasn't watching HD to begin with--just upscaled SD. If it were really HD, the programmers wouldn't need to stretch it.
