You're confusing horizontal and vertical resolution. The NTSC signal
specification has always had 525 lines of vertical resolution, only 480
of which are used for picture information. The varying figures you give
are for horizontal resolution, which does vary from about 200 lines in
VHS to 400 lines with Super VHS up to over 500 lines for DVDs. This is
an optical figure rather than a hard specification.
