If you're so disappointed with cable and singing sky's praise's all the time I don't understand why you aren't with sky. You obviously think sky is hugely superior to cable in every way. Nothing is stopping you from cancelling NTL and going to sky. It's down to personal preference at the end of the day.
I agree that the HD content on NTL is a little disappointing at the moment. It's got BBC HD and a fair few HD programmes/movies "On Demand" but a few more channels would be nice. I'm going to wait and see what happens, it's only just launched so i'll give them time. Obviously sky+ isn't capable of receiving ANY HD channels so the TVDrive has got 1 more HD channel than sky+
