Many thanks for all of your replies
Having discussed everything with "err indoors", I think we are going to ditch SKY for the time being and give NTL a shot.
As I say we are already with ntl for BB and Phone, and the service has been the best I have had of any provider (die BT!!!)
@ SMHarman - You are correct of course on the HDTV subject. It's going to be a few years yet before this technology takes a firm hold mainstream, not as if it is going to affect what I am doing here.
At the very least I can always go back to SKY if things don't pan out.
One thing I don't know, is if I am tied into a 12 month contract for cableTV, as I said I am already with NTL for BB and Phone and have been for over 3 years now. Think I'll give CS another ring tomorrow on that subject (unless anyone here knows for sure).
Many thanks once again!
