I dont think I will be doing this or trying to do it any longer. I have discovered the Mac! The mac mini that I got, “just worked” straight out of the box. I installed VLC and Remote Buddy, and I have an instant media PC, slick and smart as hell.
No setup, no finagling, pure power.

If you are not sure to go fully Linux because of the extreme amount of work involved in MythTV, pony $700 dollars toward a refurbished Mac.
