Trying to play cloud front stream in share pod

I am developing a Flash Project to be loaded into a share pod in Adobe Connect with the goal of playing Amazon Cloudfront live multibitrate streams in AC. I have a project developed in Flash Builder 4.6 using Flex sdk 4.1 and OSMF.swc 1.5, tagetting Flash Player 10.1. The best I have been able to accomplish is to play the stream locally in Flash Player but not when the swf is loaded into Adobe Connect. I have also successfully played an f4m stream hosted by Adobe when the player IS loaded in Adobe Connect. This stream is, I believe, for a video on demand rather than a live stream (the url is http://mediapm.edgesuite.net/osmf/content/test/manifest-files/dynamic_Streaming.f4m).

Any suggestions are welcome.

The code for this project is:

package

{

          import flash.display.Sprite;

          import org.osmf.media.MediaPlayerSprite;

          import org.osmf.media.URLResource;

          [SWF(width='680', height='382', backgroundColor='#000000', frameRate='30')]

          public class OSMF extends Sprite

          {

                    private var mps:MediaPlayerSprite;

                    private var track:Sprite;

                    private var progress:Sprite;

                    public function OSMF()

                    {

                              init();

                    }

                    private function init():void

                    {

                              mps = new MediaPlayerSprite();

                              addChild(mps);

  // cloud front stream that plays locally in flash player but not when loaded into AC:

                              mps.resource = new URLResource([cloudfront stream URL]);

  // non cloud front stream for VOD that DOES play when loaded into AC:

  //mps.resource = new URLResource("http://mediapm.edgesuite.net/osmf/content/test/manifest-files/dynamic_Streaming.f4m");

                    }

          }

}
