Just found this one, don"t know if it"s was mentioned before:

http://www.exit1.org/dvdrip/

"dvd::rip is a full featured DVD copy program written in Perl. It provides an easy to use but feature-rich Gtk+ GUI to control almost all aspects of the ripping and transcoding process. It uses the widely known video processing swissknife transcode and many other Open Source tools. dvd::rip itself is licensed under GPL / Perl Artistic License."

I"ll try it our on the weekend
