I totally agree with all that.
Displaying material shot in a different AR than your screen has got to be a compromise. There is no magic bullet.
A friend of mine once had a set that had a mode that would s-t-r-e-t-c-h
a 4:3 picture to fit the wide screen leaving the centre part relatively unmolested and the outer part progressively more and more stretched ie
s--t-ret-c--h
It made me feel seasick, and I would wait for him to leave the room so I could "fix it" for him
