Hmmm... Dish Network STBs are usually pretty good about slightly "shrinking" the picture so things like the score box fit on the screen. (Seems many HDTV manufacturers slightly stretch the picture so all the sets in the manufacturing run will display images that completely fill the screen.)
Also, HDNet also monitors the avsforum.com HDTV forums and there has been cases where they have solicited feedback on "score placement", etc.
Just as a check, see if you can watch HDNet's test patterns on Tuesday mornings (usually 8 am Eastern). There is a monoscope pattern that has markings to indicate the edges of the picture. If your set has the user-controls to adjust width, height, centering, (like most computer monitors), you're all set. Other sets like my Panasonic has the controls in a service mode were you also can adjust the other assorted dynamic parameters (pincushion, linearity, etc.), is fairly straight-forward but definately not novice friendly. Usually these adjustments are often covered if your set is in warranty (or you have a service contract). [A service call to "tweak" my set, surprised the technicians as to just how good HDTV can be!]
ISF Calibration is an expensive option, which some consider well worth it.
