Tvheadend

Hello

Sorry for my bad knowledge about this, but I have a question

I currently use a dreambox dvb-s2 for watching swedish canal-digital + viasat
The dreambox get's the codes from a remote computer. I use mgcamd 1.35 for this. The dns + userdetails is in the newcamd.conf file.

Now I have a server running fedora 14 where I have an installed DVB-S2 card + tvheadend.

How do I do for getting the channels to descarmble the same way as in the dreambox?
I've googled but found nothing.

I am a little bit unexperienced with this so it would be nice to know what I need or if someone can point me in the right direction.
For example do I need to install more stuff than the tvheadend program (ie cams) separetely?

Thanks for helping
