Hmm. That makes sense. So, I understand the number now, but I still
don't know why a different number had to be chosen. What was wrong with
60/1, 30/1, and 24/1?

I've searched google several more times and still haven't found out why.
I have a few links that come close.

This page says it's a stupid hack:
http://homepage.mac.com/rnc/PulldownSync.html

This page says "don't ask":
http://stream.uen.org/medsol/digvid/html/3B_videoframerate.html

This page looks promising but doesn't seem to explain it:
http://www.ntsc-tv.com/ntsc-main-01.htm

That last one does list a few books that at least _ought_ to. I might
have to go to the library and see if I can find them.
