Like, say, shorting the power supply ? That certainly
qualifies for 'doing something'.

Since you mention SCART (which I'm using too, to great
effect actually, but maybe I'm lucky with the TV I picked
out for the job) : I've been thinking that it might help
the RGB+CS as a differential signal (i.e. keep it digital,
and as clean as possible while traveling up the cable) and
only turn it analog at the other side. That is, properly,
with a transistor (not a resistor divider). I suppose it
would have to improve things a bit. Didn't get to that
either, though.
