The only problem with the BBC's composite video output (well, apart from
the lower quality) is that it's only black and white.
Fortunately, on the Master, there is a jumper somewhere near the video
circuitry which will include the colour component (normally only fed to
the RF modulator) in the composite video output.
If you want to go down this route, the BBC Master Advanced User Guide has
a list of all the jumpers. /Completely/ off the top of my head, I have a
feeling it might be J39.
