Uh oh, another case of aspect-ratio disease! Phillip, I wish you luck
on your endeavor to eradicate this instance of the disease. But it's a
plague. I've even seen TV's (LG's) with the picture over-stretched!
That means it would have fit as is but was somehow stretched even
more.

All this modern whiz-bang technology and there are ridiculous
problems. For example, syncing picture with sound, a problem solved by
the movie industry ca. 1930, is now a problem again. OK, I better stop
here.
