Kevin Rose and Dan Huard former members of the 'The Screen Savers', have started a new site/show called 'Systm'. So far the theme of the show has been hardware hacking. Its not the criminal activity type of hacking, but modifying hardware devices to do something more or different from what it was originally designed to perform.
In episode #2 of their show Systm, they demonstrate how to build a MythTV box. I have been wanting to put one of these to together for a few weeks now, I just have to make the time. Now that I have seen their show, I am sure that they have saved me several hours of time trying to customize my configuration.
Note: You will need BitTorrent to download the show.
