'says' this:
"The following abbreviations are recognized:
"‘sntsc’
" 640x480"
What is it? I'm not aware that any such thing exists.
It's NTSC with square pixels...
How do you go from 720x480 to 640x480 without throwing away 80 pixels per line?
Normally, 720x480 decodes to 720x540.

Even worse, you can have 720x480 video with a display aspect ratio of
16:9 (i.e. standard definition widescreen). In this case the pixel
aspect ratio is going to be 40:33.
Huh? "720x480 video with a display aspect ratio of 16:9" is what's on most 'NTSC' DVDs. The PAR is
32/27.
