I agree, and it would also be a huge benefit for those of us running
2.35:1 Constant Image Height projection. However, I believe the reason
they didn't do this is because the HD masters that the studios have been
striking for several years now use square pixels at 1920x1080p
resolution, meaning that the master itself only accomodates the 16:9
ratio and anything else has black bars encoded into the video right at
the master.
