Hi iag and welcome:
There are several ways to go:
Commerical (pay for it) or freeware (it’s free) or a combination of the two.
If you go with commercial, major software companies have generous trial periods with no restrictions during the trial period. Once you buy, there are no refunds.
Two of the more highly recommended companies are:
For Slysoft, I suggest you try AnyDVD and CloneDVD2.
If you are looking for simplicity of use with quality results, you will be happy with commercial (for a price). If you like playing with buttons and tweaking the process, you will enjoy products such as DVDFab HD Decrypter to remove copy protection and imgburn to burn the DVD (both are free).
There are many guides available on CDF and always remember to use quality discs such as Verbatim which is usually available locally (now on sale at OfficeMax if you live where they operate).
