Heya Cory,
Thanks for the tutorial - I think I understand the mystic numbers now.
> Total horiz line is 910/14.318e6 = 63.556us => 15.73 kHz (sound familiar?)
Not immediately obvious, but see below.
> Total vert frame is 525/15.73e3 = 33.36ms => 29.97 Hz (sound familiar?)
NTSC = 60Hz (interlaced) = 30Hz ~= 29.97Hz
For the rest of the world, the frequencies differ.
Refer to this page for NTSC/PAL/SECAM frequencies.

Previous cut/paste modelines didn't work. I'm calculating a PAL
modeline of my own now...
Cheers,
Iain
