Please note that the horizontal resolutions for all of these are not
expressed in pixels, but expressed in "lines of resolution per picture
height". This is the standard method for defining analog resolutions in the
4:3 format. To get to pixels (approximately), these numbers have to be
multiplied by 1.333.
