"The video is (appropriately) in Ogg Theora format, a video codex which is free of patent problems and supported by free-licensed video players, including VideoLAN Client (also known as “VLC”). Because this format is not yet as ubiquitous as various closed formats, your browser may not be configured to play it directly (which requires a plugin), but I had no problem playing the downloaded file in both VLC and Kaffeine."
