You can't keep 'em down. Some of the folks from TechTV have banded together to create how-to videos that are both polished and informative.
“Systm is a downloadable how-to technology show geared towards teaching the common geek, such as ourselves, various hot topics and projects. Each episode focuses on one subject and is between 10-15 minutes in length.”
The episode that caught my eye was the MythTV how-to. Having already done a MythTV installation on a Fedora box that was not easy, it was good to see there's a linux distro that comes prepackaged just for MythTV.
