trig42: I can't cancel Sky completely just yet, but I did call up to remove sports and SoHo on MOnday - they were great to deal with. Still wish you could do it on the website.
Question - is it confirmed that TV1,2,3 are in HD on MySky HDi without the HD ticket?
If it helps, an hour recording on 1,2, and 3 takes up twice as much room as an hour of prime.
