We have 2 LG, flat screens. One is a 21'' LCD, the other a 50" Plasma. Our TV input is from Direct TV. The 21'' has the standard — not HD — set top box. The 50" plasma gets its signal from the Direct TV set top box.

When viewing HD programming on the 50" screen, the picture fills the entire screen in most cases. When viewing the same programming on the 21" — not HD — TV, the picture is in the same proportion as the HD version, but it doesn't even come close to filling the screen. Each side has nearly 2 inches of unused real estate, and more than and inch unused top and bottom. It just makes no sense to me, and I've tried using the TV menu to adjust the geometry, and also the setting menu on the Direct TV box to get an enlarge image. I can't find a setting that more effectively uses the dimensions of the smaller screen. Any ideas, or is this just a limitation of non-HD signal.

You are right in thinking that it is the limitations of the the non-HD signal. The SD box is outputting a standard fullscreen signal. The shows are probably being broadcast as a letterbox image. So if up put a letterbox image in a fullscreen signal and display it on a widescreen TV you will get bars on all sides like you are seeing. There should be a zoom feature on your tv that could minimize the bars.

Thanks for your information. I guess I'm screwed unless I pay Direct TV for another HD box. I've tried the zoom modes, but they distort the image proportions more than I can tolerate.
