Sounds to me like you're asking for a world of hurt!  The composite signal put
out by a VCR is, as the name indicates, a composite of red, green, and blue
video signals, as well as timing and other signals so that only two conductors
are needed to carry the signal.  Unfortunately, an RGB monitor expects all 
the signals to have their own line.  That notwithstanding, someone's probably
built what you're looking for already.  You'd need something to split the
composite signal into its red, green, and blue components.  I can only guess,
but I'd think such a circuit wouldn't be too difficult--every TV has something
like it built-in!  If you don't mind spending $500, you could get yourself the
Video Overlay Card.  You could really do some interesting things like that;
for example, you might set up a window on the TV image in which you could keep
computing!  Also, the VOC is supposed to be capable of the 640x400 graphics
that should be in the ROM 04, so you might play with that.
