Sure, I can do that this weekend. Still, I'd really like to know the
origin of the numbers: why is video 24000/1001 instead of just 24? Why
30000/1001 instead of just 30? I know I read the reason once, somewhere,
but I can't remember.

Rich, do you know of a reasource for me to read? Or will you please
explain it to me yourself?

If I learn why I'll write up a section for the docs.
