believe it or not most people can't tell the difference between HD and analog when shown one after the other. Most people have to be shown the two side by side for them to see the difference. Through my personal experiance, the only time I could tell a difference when watching hd on my 50" TV is watching sports. You can actually tell the difference in natural and artifical turf, uniforms are brighter, people are uglier, even watching nascar was cool this weekend. When I saw 24 in HD I couldn't really tell a difference.
