Hint:  The video should play automatically.  If not, look for a “play” button towards the bottom of your screen and click that.  If it still does not play, then try this:  right click where it says “Watch Video” and choose the option to ‘copy the link address’.  Then go to your browser window and paste the link into the search box and press ‘Enter’.  This should start the video using your system default media player.
