I assume that you have standard NTSC video that you want to put on
your computer monitor.  If it is a composite monitor, it should work fine.
If you have an RGB monitor, you can make a circuit using a chip (can't remember
the number) that converts NTSC to RGB.  It was profiled in Radio-Electronics
a year or two back.  It was in their descrambling series.
However if you are starting with RF, you'll want to get a tuner--or run it
through your VCR, to get the baseband video (then go back to the beginning
of this paragraph).
Hope this helps...
