Open-source software for video

"The Worcester-based Participatory Culture Foundation just released free, open-source software for video — DTV — that allows individuals to create their own alternative TVs on the computers. DTV also allows millions of independent video bloggers and makers to bypass mainstream distributors and reach their viewers for free."

The software for Mac is available, and there's a mailing list to get an announcement when the PC version is available. As I have a PC, I can't review it yet but hope to later.
