First  do the Quick start guide on the left first!
Install all dependencies as per the MythTV dependencies tab on the left

Create a mythtv user
Use YaST to create a user called "mythtv", and create a home directory called mythtv. You should now have a directory called  /home/mythtv

Log out and log back in as user mythtv.

Install the MythTV Software
As of May 2006 the MythTV RPMs are now available from the Packman repositories http://packman.iu-bremen.de, make sure these have been setup as per the Quick Start guide on this website

Now go back into YaST, Software management ,and do a search for "myth" and all the RPM's should show up

Click on all the rpms and install. You may be prompted for some additonal RPM dependancies, depending on what you have already installed.  Click Accept.

As long as you have installed all above dependancies it should go straight through

There are a few additional themes that you might like to try. You can get them from ATRPMS which are Fedora Core RPM's but seem to work just fine via YaST. Get them Here

Now go to the MythTV setup tab above
