“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.”
