I have created a video for the ones who have problems with MythTV.The video handles some of the most common errors when installing MythTV the first time.
It also contain the installation of the HDHomeRun drivers from Silicondust on Ubuntu.
For users having the Yousee cable provider is instruction how to get it up and running on Linux (the information can be used on MS Windows as well).

In the video I also refer to a spreadsheet with all the frequencies for Yousee: dtv_multiplex
