UChannel — a collection of audio and video public affairs lectures, panels and events from academic institutions all over the world, hosted by Princeton University's Woodrow Wilson School, will disappear on November 3. Files can be downloaded until then. Their use is subject only to “Terms of Use” set forth here.
This site began in 2005, but according to their web page “...the introduction of iTunesU in 2007 made it very easy for public policy schools to post materials on-line for public access, and UChannel was no longer needed."
There are 49 items tagged "Human Rights" and 142 tagged "Law" (with overlaps, obviously)
Just a few of the recordings on offer include :

• Autonomy, Authority and Freedom - a 20th Anniversary Conference in honor of Joseph Raz's "The Morality of Freedom".
• The Constitution, Dead or Alive? - Walter F. Murphy
• Global Organised Crime - Misha Glenny, author and journalist
• Human Rights in the 21st Century - Noam Chomsky
• Challenges Facing the Legal Profession and Its Impact on Law

Download them while you can.
