Here's a past answer I provided on the topic that has some more detail: The cropping you are noticing and trying to account for is due to the "overscan" region not being visible. On some DTVs it can actually be disabled (such as with some Sony Bravia models). Content is generally created/produced to account for the various display regions which are known as the Production Aperture (full area), Clean Aperture (central ~99% of Production Aperture, but is actually defined in pixels based on the display mode), Safe Action Area (central 90% for 4:3 of Clean Aperture, with 93% for 16:9), and Safe Title Area (central 80% for 4:3 of Clean Aperture, with 80% horizontal and 90% vertical for 16:9).
