Thanks for this information. I always thought it must be somehow like this,
but your explanation makes it really clear. I guess here in Europe those
"combined Astra and Hotbird" satellite dish/LNB is what I should go for. As
far as I understand, these dish/LNB combination make a compromise on having
just one dish for 2 (relatively close) satellite against a somewhat weaker
signal because the dish is not optimally aligned with either satellite.

It thought so :-)

Hm, are you sure about that? The docs fo the Nova-CI-S says that it also can
fit 2 cards. But I haven't seen it in real life ... Anyway, I will go with
your suggestion because I prefer having the CAM's accessible from the front -
the additional CI module is a 3.5 inch module, right?

Never mind, Premiere is not what I'm looking for. But thanks for the info.

This is absolutely new to me. I read up a bit on DVB-S2 and it looks
interesting. I guess it wont take long until the cards hit the market. Am I
right in assuming that the dish/LNB I am going to buy now will be able to
receive DVB-S2? I just will have to buy one of the forthcoming cards to be
able to enjoy HDTV?
