Hi,
If I remember correctly, on one of your ns.play() calls are made with null. Something like ns.play(someVar). someVar is not always initialised (is null). That is forbidden. You must use ns.play(false) if you want the stream stopped.

name An identifying name for live data published by NetStream.publish(), a recorded filename for playback, or false. If you pass false, the stream stops playing and any additional parameters that you send are ignored.
