I seem to remember that DVD actually had a feature that allowed it to dynamically vary the pan&scan area on a widescreen movie, for display on a 4:3 TV. So you'd have a normal widescreen movie but could define - frame by frame - where the 4:3 window was located
I don't know if it was actually used much, or whether studios simply produced 4:3 discs instead. I assume many 4:3 presentations aren't simply pans anyway, there would be some zooming or other alteration of the framing
