In fact, the palplus standard makes it possible to broadcast 16:9 images in 4:3
format with black bars on top and bottom. If you have a palplus television set,
it will extract extra information from the black bars and use it to enhance the
image. However, this is not supported by any capture card, so what MythTV does
is just to cut of the black bars. (4:3 zoom)
