title: currentSrc not working inside jquery plugin
body: <p>"currentSrc" is the only option I have to switch source src in html5 video in with multiple source (*.mp3, *.ogg etc.)</p>
  
  <p>"currentSrc" throws "undefined" if I use inside Jquery.
  But it works fine, if I call this in the html page.</p>
  
  <p>In detail:
  My Video Source:</p>
  
  <pre><code>&lt;video width="630" height="354" id="video1" class="video1" poster="asserts/poster.png" controls="controls" data-name="demo video" data-uid="57fb2708"&gt;
          &lt;source src="http://static.clipcanvas.com/sample/clipcanvas_14348_H264_320x180.mp4" data-quality="sd" /&gt;
          &lt;source src="asserts/samllfile.mp4" data-quality="hd" /&gt;
          &lt;source src="http://static.clipcanvas.com/elephants-dream.webm" data-quality="hd" /&gt;
          &lt;source src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" data-quality="sd"/&gt;
          &lt;source src="http://video.webmfiles.org/elephants-dream.webm" data-quality="hd" /&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>Get current video URL</p>
  
  <p>Javascript in the html page (which works fine):</p>
  
  <pre><code>myVid=document.getElementById("video1");
      function getVid(){
          alert(myVid.currentSrc);
      };
  </code></pre>
  
  <p>Line inside Jquery (throws "undefined"):</p>
  
  <pre><code>alert($hdVideo.currentSrc);
  </code></pre>
  
  <p>Please help me out...</p>
