I am using Mac OSX 10.9 (Mavericks) and the browser Safari 7.0.3. All the videos on the tcm.com site do not work. On the tcm homepage (tcm.com) in the upper middle there is no video, just a message that says "plug-in failure". All the other videos on your site, i.e. video on demand; video clips from a particular film - there is simply the revolving arrows that denote the film is downloading, only it never does download. What plug-in is required for me to download and view these videos?
