I haven't ripped a DVD since I last had a Windows PC with a DVD drive in it -- something like 5 years ago now. But: I used to use AnyDVD, which looks to have been updated in December, so still current. Can't comment on whether it's still good, though.

I don't actually have a DVD drive in this (Linux) PC -- the case doesn't provide forward-facing drive bays, probably because there's less and less call for them, so I don't know what I'm going to do to rip DVDs (or CDs) these days.
