You can have a DVB-T/C/S card plus a analogue card in the same m/c.
You are best looking for a card that has hardware encoding of analogue 
signals,
  1 less load on the cpu,
  2 you dont have to rely on getting a compatible software encoder.
Some of the old video editing cards will work as well, which can be 
picked up quite cheaply.

Ebay have a good selection of dual and quad lnb for between £10 & £20. ( 
1 lnb required per channel )
Also depending on which satellite your pointing at youll need to decode 
the stream (Sky)
