What connecting cables are you using.

I assume s-Video to SCART at the transmitter as a SKY+ box does not have
S-Video out via SCART.

Are you using SCART to S-video at the TV end or are you using a SCART to
SCART lead into an S-video enabled SCART ?

If you are using a SCART to SCART lead it could be crosstalk in the cable
from the output of the TV's tuner.  Disconnect Pin 19 (video out) of the
SCART lead at the TV end and it should cure the problem.

If it doesnt then contact me directly and I will try to resolve the
problem.
