DVD ripping are two words used when extracting video from DVDs. It is analogous to CD ripping to extract audio from CDs. While DVD ripping has been promoted widely on IBM-compatible PCs, tutorials for Macs (specifically Mac OS X) are difficult to come by. This tutorial will explain how to rip a DVD on Mac OS X for the pruposes of backing up to another DVD, what resources you will need, and how to go about it. Instructions for backing up DVDs to other formats (e.g. Video CD, DivX) can be found elsewhere on the internet.
