Mythtv Newbie Setup Problems

Whilst I have been using Suse for a Number of years (currently 11.1), I am purely a desktop user, and have no idea about terminal or command line use. I have downloaded Mythtv from pacman but have no idea how to set up the backend or data base. Everything on the web just goes straight over my head. I have my tv card (Hup Nova T dvbt 909) working perfectly in Kaffine, but want to build a HTPC box based on Mythtv.
Please can you help?
