dvd ripping the animatrix?

[seebol]

As recommended in a previous post, I've started using Handbrake to back up my dvds. But I just inserted the Animatrix, and for some reason it won't let me rip title 15, or a lot of other titles for that matter. Why? Is there anyway to rip these missing titles?

DVDBackup has worked on every DVD I've tried, provided there's enough disk space ;)
