Cannot remove VideoEvent listener actionscript 3

Question

Hi all,

I have a simple swf which create flvplayback object and load from time to time an flv, replacing the old one. I manage everything in a wrapper class, identified with mdcVC in the code below, with a variable FLVPlayback in it.

I notice one strange thing, before loading a new flv, the old one is replaced and the listeners removed. However in the fragment of code where this happens seems that the VideoEvent is not removed.

   trace("listener:" + mdcVC.flvPlayer.hasEventListener(VideoEvent.STATE_CHANGE));
   trace("listener:" + mdcVC.flvPlayer.hasEventListener(IOErrorEvent.IO_ERROR));
   trace("listener:" + mdcVC.flvPlayer.hasEventListener(NetStatusEvent.NET_STATUS));
   trace("listener:" + startPlayButton.hasEventListener(MouseEvent.MOUSE_DOWN));

  mdcVC.flvPlayer.removeEventListener(VideoEvent.STATE_CHANGE,onFLVStateChange);
  mdcVC.flvPlayer.removeEventListener(IOErrorEvent.IO_ERROR, onFLVLoadError);
  mdcVC.flvPlayer.removeEventListener(NetStatusEvent.NET_STATUS, onFLVLoadError);
  startPlayButton.removeEventListener(MouseEvent.MOUSE_DOWN,mdcVC.startPlay);

   trace("listener:" + mdcVC.flvPlayer.hasEventListener(VideoEvent.STATE_CHANGE));
   trace("listener:" + mdcVC.flvPlayer.hasEventListener(IOErrorEvent.IO_ERROR));
   trace("listener:" + mdcVC.flvPlayer.hasEventListener(NetStatusEvent.NET_STATUS));
   trace("listener:" + startPlayButton.hasEventListener(MouseEvent.MOUSE_DOWN));

This the output:

true
true
true
true

true <----- (why is that ??)
false
false
false

Are you sure you didn't add that event twice, one with useCapture and another one without it? Because if that's the case, you'll also have to remove it twice.
