DVB-T stands for "Digital Video Broadcast - Terrestrial", DVB-S for  
"Digital Video Broadcast - Satellite".

As you connect a DVB-T card to a freeview aerial to receive digital  
freeview TV, you connect a DVB-S card to a satellite dish to receive  
digital channels on the Sky satellite. Some of the channels on Sky  
are encrypted, mostly the "for pay" ones, but the selection of free  
channels is compatible with those available via freeview.

As I understand it the Sky dish is mounted on the wall & mounted on  
an arm in front of it is an "LNB". A co-axial cable connects the LNB  
to the DBV-S card; dual- and quad-LNBs are available which allow  
multiple co-axial cables to be connected to multiple TV cards. Can  
anyone confirm whether this is correct?

Ah, sorry - it wouldn't. I didn't see that mentioned in the post I  
replied to.

I believe the you could fairly easily & cheaply receive some  
satellite channels, then.
