onIoError followed by 301: Unable to load plugin

[GoogleCodeExporter]

I am using cuepoints combined with seek. The idea is to launch a video and have 
it pause to present a question or questions on a given cuepoint.
I also am simply playing videos. I use two separate function calls to either 
play video with questions or just play video. If the user has not finished a 
video, a decision alert is presented to continue from last point or start at 
the beginning. 

the errors are unpredictable. I cannot reproduce them by following a set of 
steps. They happen when they happen. Below is the errors:

I run flowplayer on an overlay. The code is here:

 <script language="javascript">
      $(document).ready(function (content) {
      $("a[rel]").overlay({
      effect: 'apple',
      expose: '#111',
      load: true,
      onLoad: function() {
      $f().load();
      },
      onBeforeClose: function() {
      seekTime = $f().getTime();
      var now = new Date().getTime();
      LMSSetValue("cmi.suspend_data",Math.floor(seekTime));
      LMSCommit("");
      LMSSetValue("cmi.core.session_time", millisToCMITimespan((now - mStart) + timeCompleted));
      //alert("seekTime: " + seekTime + " now: " + now + "and mStart: " + mStart + " and timeCompleted: " + timeCompleted);
      },
      onClose: function() {
      player.unload();
      checkItemBrowserClosed();
      }
      });
      });
    </script>

Has anyone seen something similar to this?

Please note that there ajax calls intermixed with the flowplayer javascript.

Notice error 100 but the text is null. I have no idea how to fix this. The

This error causes cuepoints not to load. It happens with both functions, but I 
need cuepoints to run.

Please provide an example online. Im pretty sure you posted this in the forums 
correct ? 

$f.fireEvent ["onError", 301, ": unable to load 
plugin...yer.controls-3.2.8.swf'"]

it can't load the controls plugin it seems.

Hi Im going to close this , I have not been given an example page please update 
if needed, it looks to me you aren't loading the controls correctly.
