Paul pointed over to ShrinkTo5, an open source replacement for DVD Shrink, and blogs his experience. Basically it's attempting to be a legal version of DVDShink, which means it doesn't seem to be able to or willing to deal with encrypted DVDs, or at least without some modifications. Interesting read... for now I think I'll stick with DVD Shrink, though this looks like it might have potential. I'll play with it at home and see how it does.
