why was 720 chosen for DVD-Video width when players have to resize, anyways, be it 16:9 content as well as 4:3?

thanks!

i can see the need for a consistant sampling rate number, but at the same time, some of it flies over my head

Players don't always have to resize. A 4:3 DVD played on an SDTV will be displayed without any resizing. A 16:9 DVD played on a widescreen SDTV will likewise be displayed without resizing.
