Hi Velvetee.
We have Sky HD ~ Full sports package, no multi-room, no film or childrens channels, no internet or phone from sky and over the past year we have had to phone Sky 4 times to get the box re-set as it keeps freezing. We pay £49 pcm and have also been told this is going up. I am seriously considering dumping Sky. We have a tv in the spare room that has built in freeview and Sky have stopped broadcasting Sky Sports news on freeview as they want people to pay for their packages (greedy B'strds!!)
The thing about going across to B.T. or Virgin is that they have to buy the rights to the programmes from Sky. So, although you have more control over what you pay to watch and don't have to sign up for set packages as you do with Sky, there are few real monetary benefits to changing.
