In case there are any tinkerers on this forum, I've decided to post dvdbackup compiled statically linked to libdvdread and libdvdcss (static linking builds the libraries into the executable, so that you may share it without having to worry if the user has those dependencies installed), along with instructions on installation, usage and compiling. It's a command-line executable, and is the foundation for Hades, the new DVD ripper interface for MacOS X. You can grab it here.
