Huh? "720x480 video with a display aspect ratio of 16:9" is what's on

'NTSC' DVDs.

Huh? The vast majority of DVDs I've handled were 4:3 then maybe
letterboxed
to only show some wide-screen size (like 2.33:1).


This is the opposite of my experience where widescreen DVDs were encoded
anamorphically and were de-squeezed to the correct DAR. Very few were 4:3
with burnt in letterboxes.

The pre-2000/2001 DVDs labeled "Wide Screen" were letterboxed 4:3 DVDs that are also pillarboxed on 16:9 screens. I still have a couple of them. DVDs are not optically anamorphic in the sense that CinemaScope is anamorphic. They were simply sampled with the highest resolution available to flying-spot scanners of the era. I don't think the word "anamorphic" applies because 720x480 (or 720x576) are not pictures, they're data arrays populated by pixels (data).
