Welcome to MyCE
Safe to buy but can it copy your DVDs?
The problem is, is it able to deal with copy protection which you will find on most commercial DVDs???
I use AnyDVD in combination with CloneDVD2...a more or less perfect combination because it is continuously updated.
There are one or two alternatives, which are free but not updated as quickly.
You could try ShrinkDVD (which is FREE, but not really up-to-date)
