Can't use more than one instance of ExpressionPlayer in a Silverlight app?

  Hi all,
  
  I'm using the Silverlight Player template from the Expression Encoder to play smooth streaming movies and works without a problem, until I add another instance of the player to my application. When I do that, only one of the instances will play the movies. The other won't show anything.
  
  From debugging the player, I found that sometimes m_mediaElement is null in TogglePlayPause (in MediaPlayer.cs):
  
  

  protected void TogglePlayPause()
  {
  	// Change current play state depending on current state.
  	if (m_mediaElement != null)
  	{
                .....
  

  
  Anyone experiencing the same problem?
  
  Thanks.
