      playctrl.SetPreferredFilter(PreferredFilter.MPEG2Decompressor, Constants.PreferredFilters.LEADDefault); 
 
      // the default mpeg2 decoder should be the LEAD MPEG2 decoder now 
      // the filter names are not case sensitive, so ignore case in the compare

                 Constants.PreferredFilters.MPEG2Decompressor, true) == 0);
