Is this the intention of AnyDVD?

If I have AnyDVD installed and running and I have a copyprotected DVD and I want to do a 1:1 copy (let’s say the DVD is less than 4.7gb) onto a 4.7 gb DVD-R I can do so with a program like Primo DVD or Nero’s plain old Disc Copy function? There is no longer a need to use programs like Smartripper?

Yes, if you have AnyDVD running it will decrypt your protected DVD on the fly. In this case you do not need to use programs like SmartRipper.
