Actual full screen is 720 x 540 computer-pixels (TV uses rectangular pixels so the computer pixels have to eventually be squished to a different vertical dimension). There is a "safe area" of 640 by 480 (computer pixels) centerd within the 720 x 540 where everything needs to be to ensure it's visible onscreen. The extra area outside the 640 x 480 is to accomodate the fact that TV screens are not always perfect and sometimes are shifted. Just FYI.

Before they made me they broke the mold!
