Free DVD copying software recommendations?

Hey gang, I've been using the same old copy of DVD shrink to rip DVD's for like 5 years now, but I have a new computer running Vista 64 and thought it might be time to update with a newer free download DVD ripper/burner. Obviously there's tons out there so I was hoping to avoid the sifting process by asking if anyone here has a tried and true freebie they'd recommend?
