Breaking copyright protection is against the forum rules. Since you wouldn't want to violate the rules, I'm going to assume that you're not talking about retail movies.
DVD ripping your own legal copy is okay but don't distribute it - it is like making a backup with the original. DVD re authoring a retail movie is illegal and DVD shrinking a retail movie(s) are also illegal.
No, breaking the copyright protection isn't ok, not even on your own copy. You should read the FBI warning at the beginning of the DVDs. It's not only illegal, but it's against the forum rules.
