Typically every commercial DVD uses CSS protection. You have not wasted your money, you just need to spend a little more on another product called AnyDVD. Which is available at slysoft.com along with CloneDVD.
In short, AnyDVD stays in your taskbar and decrypts CSS protection and all sorts of other rubbish the manufacturer puts on the disc and allows its brother CloneDVD to copy it.
