Hi, I've been reading a few recent threads on DVD burning, but I'm still a bit confused. Assuming I have a mac that can burn dual-layer DVDs and assuming that I have a nice big pile of blank dual layer discs, what's the best (easiest) way to back-up my movie DVDs without losing anything. I want exact copies -- menus, extra features, subtitles, languages, etc. An exact carbon copy at exactly the same quality as the original... Oh, and I want to install as few applications as possible. Is it possible to do this without installing anything -- just using OS X, I mean? Steve.
