Handbrake just worked for me, and produced wonderful results.
So i was able to backup quite a recent DVD without hassle. Just a few clicks.
Others (on jaunty) wouldn't work for me at all with this DVD. Actually, lsdvd wouldn't work, and dvd::rip seems to rely on this. So dvd::rip wouldn't work. k9copy didn't fare any better (just crashed), and I was almost giving up on the possibility for it at this time, when I tried one last possibility. Handbrake.
Isn't in the repositories (i think) but should be!
