Yes Jock you are right. I used to have a full motorised system. But a twin LNB setup(13 and 19 East) is the best bet these days. Ok you might miss the stuff on Hispasat30E or Sirius 5east and Thor 1west.
But to be honest most porn and football, boxing etc is free on a dual lnb system with hotbird13E and Astra19E. My card has not been updated for months and yet I still get the MTV and VH1 feeds which means I have a choice of twelve versions of VH1 and MTV all designed to be feeds for cable head-ends in Europe.
