I won't watch a scope film in 4x3, for that very reason. I do know
about super 35, and the various aspect ratios that can be derived. They
do show more on top and bottom, than the cinematographer intended, when
shown in 4x3, instead of cropping the sides. But, we were discussing
anamorphic DVDs, and I was trying to keep it simple. ;)

My point is that you can see accurate aspect ratios of 2.35:1, and
1.85:1 films, on anamorphic DVDs. So, I wasn't sure what was meant by
anamorphic DVDs not supporting those aspect ratios, but only 16x9. It
would probably be too complicated to have electronic reproduction using
a host of aspect ratios, unsqueezing them at different rates, in
consumer equipment, and thus it is not used that way on DVDs.
