Nevermind, got it working
Used direct S-Video from Sky+ Box in to the Tuner - all happy working now - and normal phono cables.
Have one glitch now - a whit"ish" bar at the bottom of MCE Live TV, not sure whats causing this? Its like an overlay... happens on all channels.
Is this due to
a: Cable
b: tuner
c: S/W
d: Sky+ being Sky.
