I ended up getting MacDVDRipper Pro at one point after MacTheRipper wouldn't work on my latest upgrade; FWIW 4.0.7 works for me on MacOS 10.8. (They seem to have it half-price at the moment, not sure if that's a special or permanent drop. You can also download and test it before you buy.)

I need to wait on hearing about a few more bits of software before I try the upgrade to 10.9 - @littleheaven, thanks for your reports!
