It is for decoding of encrypted channles (you need a smartcard too).

Definitely yes, you need 2 cards for timeshifting. One of them must be
expensive card, the other the low budget. But to clarify it, this is true 
if you want to do timeshifting over the TV-out of the DVB-S card. With
only one card you can still play the files with xine under X-Windows, but
you need a monitor (or use the TV-out of the graphics card).

I suppose that DVB-boxes of any vendors will run in sweden? If this is
true then the DVB-C with linux should run too. But DVB-C is not well
supported with vdr (because the author do not have cable).
