DVD Ripping Freeware?

Is there a reliable DVD ripping suite out there for free? I'm really not sure about DVD Shrink - it's been recommended to me but it comes in a zip folder and I'm wary of that kinda thing. All I'm looking for is a reliable, uncomplicated suite with a straightforward installation, because I've dowloaded a couple of suspect files and I don't want to go through that again. ^^;
