 * Have you tried deactivating other plugins to see if something might be conflicting?

 * I’m seeing the same error. I have tried deactivating every plugin except this
   one and also activated WordPress default themes like TwentyThirteen, etc., and
   I still see the error: “ReferenceError: videojs is not defined”
    It specifically
   refers to:
 *     ```
       <script type="text/javascript">
       videojs.options.flash.swf = "http://www.specialtyheating.com/wp-content/plugins/videojs-html5-video-player-for-wordpress/videojs/video-js.swf";
       </script>
       ```

 * Thanks, this is actually fixed for the next version already which is hopefully
   coming soon. Although the error is annoying, it shouldn’t have any affect on 
   your site.
