I first heard about this new Internet-TV show on the "This Week In Tech (TWiT)" Podcast. Kevin Rose, one of the presenters of Systm is a regular guest on TwiT. Systm just released their 2nd episode. This episode is all about building a Linux based MythTV PVR. They go into quite a lot of detail and explain stuff quite well. The first episode showed how to build a box of tricks that would pick up wireless video cameras. This show is very cool and is very professionally produced despite being free to download. You will need a Bittorrent client to download the show, I'd recommend Azureus. If you like Systm you should also check out From The Shadows.
