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

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