Taking video from a DVD & Making it Editable
A musician family member who edited video on his Apple PowerBook G4, swore by Handbrake. Handbrake is now available cross platform OSX, Linux, and Windows (through Windows 10). Much this musician's work in later years was ripping and repackaging DVD footage - and what he particularly liked was that Handbrake was "bulletproof." It even ripped mini-DVD AVCHD video from my Panasonic hand-held, before we were calling it H.264. Downloads available here: Handbrake Downloads
