As folk have said above you are actually seeing the program as it was meant to be seen, in 16:9, not in 4:3 with the right and left edges cut off.
As someone has said though, if you change it to pan and scan you'll fill the screen, but having it 4:3 letterbox will show you the actual proper full size, full aspect ratio picture.
Get a widescreen tv

you'll never ever look back once you get one.
