Boing Boing just announced the launch of DTV Beta, “an open source video publishing/viewing/downloading tool”. This is the player component of the Broadcast Machine, a tool that enables users to create their own video channels. I suspect that DTV has been out since June, but I just haven’t had a chance to follow-up.
So far it looks great! DTV includes a channel guide and allows users to easily subscribe to video RSS feeds. Very slick, be sure to check it out.
