Interestingly, the old dvd (or was it the laserdisc) for Willy Wonka said "matted" on the back. I saw Independence Day on one of the Encore channels recently (4x3), the people were not visible in that shot of the white house. It definitely had the pan & scan appearance as I previous wrote about seeing it on tv. This leads me to think the full screen dvd is just pan & scan.
There's a facebook group called "People who like fullscreen more than widescreen are truely dumb." (I don't know if they can cansider themselves TRULY smart.)

Does anyone know what movie the picture is from. It looks a lot like Coruscant in Revenge of the Sith but it's not, plus any full screen Star Wars movie will always be pan/scan. I wish the image was bigger so I could better tell. But that's the kind of image that actually makes fullscreen look better. You actually see more of the people (ok just their legs) in the 4x3 version. And the extra space on the sides that contains nothing looks pointless, especially with those black bars on a standard tv. (truly dumb to use that example for a pro widescreen group)
