I don't know if you're trying to use the box for subscrition channels or just the free ones. I use a Topfield 7710HDPVR in Menorca to record free channels with it's twin tuners, I can use an old
Sky card in a Trex 4.6 cam which enables pairing. I only use it for CH4 HD as you can get the rest free anyway by tuning to the freesat frequencies including ITV HD. If you ask it maybe possible,
I think!, to record subscrition
Sky with one of the many boxes like the Topfield without paying the extra £10. I update the sky card in a Grundig box which does lose signal at night even with a 1.8 dish but the Topfield is fine on all my channels. (My dish has twin LNB's offset for 13 and19 with 28 at the centre).
