DVD aspect ratio control

I would love it if DVD manufactures would provide a single button on the
remote to cycle through the standard aspect ratios. ie
4:3, 16:9, 1.85, 2.35 etc on the assumption that you had preset in the
setup menu your particular monitor aspect ratio, 4:3 or 16:9. And such a
control should work no matter what type of file type you are playing. My
Topfield STB does this where you can cycle through centre cut (4:3 image
pillaboxed within the standard 16:9 transmission) etc - so easy.

Ta and good night!
