SubtitlingLanguageControl: How to turn on/off subtitles (ClosedCaption)?

Question

Hi,
does anybody has an practice example to turn on and off programatically the subtitles?
I've developed an accessibility profile manager, and this is one of the settings I wish to control.
I'm trying to understand how SubtitlingLanguageControl works, but I feel stupid because I have no idea on how put it to work : (
Regards,
Alemao

I've found:
   * Ativa ou desativa a exibi��o de legendas (ClosedCaption).
   * Origem: MHP Wiki - http://mhpkdbwiki.s3.uni-due.de/mhpkdbwiki/index.php/Presentation_control
  public static void setSubtitling(boolean PbVisible)
    Player oPlayer = B4Player.getPlayer(); // Pega o player
    if (oPlayer != null)
      // Busca o controle de legendas
      SubtitlingLanguageControl oSubtitlingLanguageControl = (SubtitlingLanguageControl)oPlayer.getControl("org.davic.media.SubtitlingLanguageControl");
      if (oSubtitlingLanguageControl != null)
        // Busca as legendas dispon�veis
        System.out.println("SubtitlingLanguageControl encontrado");
        String[] aLanguages = oSubtitlingLanguageControl.listAvailableLanguages();
        if (aLanguages.length > 0)
          // Se encontrou alguma legenda dispon�vel
          System.out.println("Legendas dispon�veis");
          oSubtitlingLanguageControl.setSubtitling(PbVisible); // Ativa ou desativa conforme o par�metro
        else
          System.out.println("Legendas n�o dispon�veis");
      else
        System.out.println("SubtitlingLanguageControl nao encontrado");
  }XletView doesn't support this, as many other controls like BackgroundVideoPresentationControl and GainControl : (
