title: How to apply a callback to multiple elements?
body: <p>I have this following callbacks. But if I start my player is going to show me always the second callback. How can I make a callback and show both videos random?</p>
  
  <pre><code>callback('{"video": {"mp4": "http://c0026122.cdn1.cloudfiles.rackspacecloud.com/193807.mp4", "webm": "http://5860e9e4db2f4cebe1e6-cc12bb9b5e092d34d0fadb7ce5f280a3.r47.cf1.rackcdn.com/193807.webm", "title": "Touch"}}');
  callback('{"video": {"mp4": "http://c0026125.cdn1.cloudfiles.rackspacecloud.com/064915.mp4", "webm": "http://a95a046574a64b9ea43b-53264ce826f5cfe73ee69a0c3c37eccc.r68.cf1.rackcdn.com/64915.webm", "title": "Grace / Fever / Dinner / Heart to Heart / Videogame"}}');
