HBO locks down fair use rights, kills OnDemand copying

In an apparent effort to "protect" their content, HBO will be adding copy protection technology that will keep viewers from making copies of their programming.  It will allow viewers to make a single copy of standard HBO programming and will completely disallow copies of any OnDemand programming.  Want to watch that episode of Six Feet Under on the plane?  Not gonna happen.  People are already on HBO about the fact that this caps fair use, but they don't seem to care, as they are looking to protect their content from the evil people who want to watch it.  One step forward, two steps back.
