Hi dragoshenron,
maybe this presentation on youtube may help (it is in dutch). It only shows how to setup oscam with the use of one (CD) card, but adding the second is easy. It did help me getting started with oscam after using cccam for some time but cccam crashed very often and as this is the only source of watching TV for my family, it should be stable. Google is your friend in tuning.

Hope this helps.
Cheers.
