hello and welcome to the site
Well, perhaps you could tell us what you've learnt so far by browsing and searching the forum. Maybe you only wish to backup up the main movie or perhaps you want to do the whole DVD. Maybe you're just interested in Karaoke on DVD, or is it DVD Audio? Does your region use flippers? Are the movies split over two discs? Or are they dual layer. Are they CSS protected? DVD plus or dash R formats. Playing in a PC DVD-ROM or a set-top? Any issues with compatibility for set-tops?
What do you to achieve besides best and easiest which is a matter of opinion anyway?
