89-98% (Checked, SVT1-2, Discovery, TV4 Komedi, Canal+ Hits)
I have a 4-way powered splitter connected to those cards, and kind of 
expensive cables (gold connectors and such).

I'm not sure if the CI-interface works, but they do look a like. Also I

That made a bit of differance.

I got my cards from 

And the CI-cable from Elfa.
