First clue. It isn't on TV.
It's Systm. Kevin Rose and Dan Huard, two refugees from the long lamented TechTV, have started Systm. They are also thebroken. System is a videoblog on steroids, television without commercials. It's tech for tech heads and newbies alike. In short, it's what TechTV used to be; ground breaking but informative and accessible by many, many people.
Systm is two episides old, but both Kevin and Dan have a decent amount of air time between them, so the polish is almost there. The information, however, is top notch. The first episode has both of them running around Silicon Valley looking for open video nodes. The second episode demonstrates how to build and configure a MythTV box.
