"Composite video and audio" IS baseband NTSC. What you're looking for is
something that takes the NTSC-modulated signal on channel 3 or 4 coming out
of the VCR/cable box and converts it to baseband - in other words, a tuner.
Tuners are available all over da place - you can pick 'em up from the surplus
stores for a song (and maybe a dance or two, depending on the quality of your
singing). Feed a solid-state tuner a little bit of the right voltage(s),
and you'll be able to pick the video and audio right off (usually from separate
jacks - or did you want to leave the audio in the video signal?).
