dvd43 isn't going to help you; it's deadware, and, by itself, it's completely useless and can't handle newer protections. So it's not going to help you with Nero Recode. Dvd43 will help you with 1-Click--but not Nero Recode.
If you want to use an on-the-fly decrypter, I recommend and use Anydvd. Try the 21 day free trial at www.slysoft.com
The program in Nero you'll want to be using is Nero Recode in all likelyhood.
