How to Copy a DVD  Wired magazine's How-To Wiki covers the step-
by-step for duplicating a video DVD using free and pay-for
software. They recommend using Mac The Ripper to rip the DVD
(sans copy protection) to your hard drive. (We also like Drive-
in.) From there, you've got to purchase something like Roxio
Popcorn or Toast to burn a DVD player-friendly copy;
alternately, make it iPod/media center-playable using the free,
open source LH favorite, Handbrake. How do you back up and copy
your DVDs? Let us know in the comments.  Burn a DVD on Your Mac
