Miro

Miro, formerly known as Democracy, relaunched this week and got rave reviews, including this one from Next 100, a prominent video topics blog:

"Miro is an open-source Internet TV application that combines a media player and library, content guide, video search engine, as well as podcast and BitTorrent clients. Developed by the Participatory Culture Foundation, Miro aims to make online video “as easy as watching TV”, while at the same time ensuring that the new medium remains accessible to everyone, through its support for open standards. Described by some as the “Firefox of media apps”, the resulting effort is a slick looking and easy-to-use application — not a mean feat when dealing in open-source methodology — that gives Apple’s iTunes (the default media player and video podcast client for many) a genuine run for its money."
