Keith to the rescue again, if you put a 2 x 220ohm resistors (i.e.
440ohms which is what I had handy) across the signal and ground the
cameras work fine.  Worked ok with a 220 or 100ohm on it's own but
not sure what effect this would have longer term (Keith?).  I'm
guessing it should be as high as possible 1Kohm gives distortion
though.

Also make sure you get a signal on a TV first if you are using scart
to scart connector as some of the ground pins may not be commoned
together.
