public void HasCacheDialogExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // reference the MPEG2Transport target format from the collection of the target formats 
      TargetFormat fmt = capturectrl.TargetFormats.MPEG2Transport;

      fmt.UseFilterCache = true; 
 
      // check to see if the format has a multiplexer dialog for settings  
      if (fmt.HasCacheDialog(TargetFormatDlg.Mux))
