No, typical 4:3 TVs overscan by about 5% on all sides, including top and bottom. For the DV sample matrix of 720x480, this means that the central 648x432 pixels are visible on the screen.

SomeJoe,
In that case, how do the resizing methods that you described above give accurate output when they do not appear to make any attempt to compensate for overscan on the top and bottom of the video. I understand, with NTSC for example, that you are cropping 8 pixels on each side and that compensates for TV overscan on the sides. But why then are you not cropping anything on the top and bottom?
