WARNING: Unless the RGB signal is NTSC compatible with regards to the frame
rates, you will not be able to record the output.  All other RBG frame rates
MUST be sent through a RGB to NTSC converter.  The only RGB that was even
close to NTSC was the IBM CGA standard.  All analog RGB rates that I know of
are not NTSC compatible.

The exception is the Amiga series of computers.  Those were designed for video
work in mind.  So you can purchase all kinds of various boards and external
options for getting NTSC output in composite or S-video.

But the IBM-PC compatible and Sun Workstation RGB outputs are not NTSC rated.
