you can also try dvd-cloner v it bypasses encryption and shrinks dvd all in one software or you can remove certain things like extras if you want http://www.dvd-cloner.com/dvd-cloner/
DVD fab 5 platinum.. works for me.. Even on the new copyprotection system. DVD shrink only went to a certain version and I think DVD fab bought them out. that` s probably why the shrink wont work, cos its an older version.
i like clone dvd2 and any dvd also try removing any extras audio languages just do the movie only that takes up a lote of unwanted disc space hope this helps
