Dong-Lok is of course right.  I got this started by describing the formats
accepted by two hardware MPEG implementations.  Somehow I forgot I got my
numbers screwed up and worked forward from the 640x480 VGA numbers rather
than the CCIR numbers.  The chipsets I mentioned do indeed take the real
MPEG SIF resolution (352 x 240) and the Px64/JPEG CIF resolution (352 x 288).
