DTV: Internet TV is a neat little beta application for downloading, subscribing and watching internet "channels"—kind of like vodcasting.
DTV is a new, free and open-source platform for internet television and video. An intuitive interface lets users subscribe to channels, watch video, and build a video library. Our publishing software lets you broadcast full-screen video to thousands of people at virtually no cost. The project is non-profit, free and open source, and built on open standards.
As of right now it's OS X only, but they've got a Windows version coming soon.
