I've managed to tape video from the GS composite output on a cheap machine
however, when I use a high end deck (Mitsubishi SU-82 or Panasonic AG-1960),
I get poor horizontal sync.  Since the GS doesn't put out a spec NTSC
signal, it makes sense that recording would work on some machines while
not working on others -- slop on machines varies.  Via a VOC I have no
problems -- except the resolution sucks.
