Using CSS+Region Free, I used
Nero 7's Nero Recode to backup most of my DVD's. Nero Recode works flawlessly with CSS+Region Free, and allows me to backup either the entire DVD including menus and extras or just the main movie. For the entire DVD I use a Dual Layer disc and haven't had any problems yet. I've even backed up some very recent movies like "Batman Begins" "Sky High" "Stealth" "Fantastic 4" all with no problems or issues. I'm very impressed with CSS + Region Free and it's compatibility with Nero. I use Nero almost everyday for different tasks, and I find it very convenient to be able to backup my DVD's with the software I am most familiar with.
