         <li>Category (media, message, etc.) expansion does not work
           for mime types which have no associated filter. This is
           quite often the case for video types (so they won't be found
-          under "media"). The workaround is to add them to the
-          ~/.recoll/mimeconf file with the rclnull filter, for
-          example:
+          under "media"). <br>
+          There is a possible imperfect workaround. Create a filter
+          shell-script named rclbad inside the filters directory, with
+          only an 'exit 1' inside it, make it executable and associate
+          it to the video types, in ~/.recoll/mimeconf:
