I have been using Mac the ripper with some success what is the best system for a Mac. any help would be appreciated
Other than commercial and what you are using now there is Handbrake. It only does css decryption and I think the latest version only runs on Leopard.
Apple has no future :(…
Take a look at dvd2One it has both PC Widnows and Mac OS-X versions http://www.dvd2one.com/
