    I just got the HD package and was watching some stuff with my funny little honey and she asked me why sometimes the picture shrunk down to a box and sometimes it was full screen.

    I know I should know this...But I don't.

    Little help?

    Not all shows on HD channels are in HD. In that case they will have black bars on the side to show the picture in the correct 4:3 standard screen format.
    For some reason HD channels will show a program with black bars on all sides, sometimes referred to as "postage stamp". I don't know the reason for this, since the original picture should fill the widescreen HD aspect ratio. Someone else may provide some more information on that.

    When there's a letterbox SD broadcast, it'll end up pillarboxed on a 16:9 screen since it's a 4:3 program, but since it's letterboxed as a 4:3 program it already has bars on top and bottom; in the end you get a "postage stamp" display unless your television or receiver allows you to zoom/stretch the image.

    Postage stamp is shown because the show is really a widescreen image inside a 4:3 aspect. Here you might be able to use the TV controls to stretch and expand the image to full screen. However, the PQ will suffer.

    One other item.
    Some movies are filmed in a wider format than HD television. In this case there may be bars on the top and bottom of the screen. Showtime does this. I usually don't see this on HBO which means that HBO is cutting off the sides of the picture.

    So when a station runs commercials, if it fills the entire screen, then it was filmed in HD and if it shrinks down, then it wasn't.

    Thanks everybody.

    Except TNT-HD, they stretch everything to fill the screen, wether it is HD or not, including commercials.

    Well, and this will sound stupid I know, How do you know when it's in HD. Is it appearance only? Clarity of the picture?

    Typically it is just the clarity of the picture that sets it apart from an upconvert .
