I believe that I may have encountered the first form of DVD copy protection to stump DVD Decrypter...although in all fairness, I am the second person to run into the problem.
Has anyone had any luck making "proper" 1:1 copies of either the Lord of the Rings: The Two Towers, or Volume 1 of the Simpsons 3rd Season DVD set? If so, please list your DVD-ROM/DVD-Writer, firmware, and software involved.
For my part, any copies I've made of the Simpsons 3rd seasons DVDs have resulted in a DVD which will play fine up until you try to load up an actual episode, and then after that, it hits me with an improper region code screen, which is crazy since the region coding was ripped out by the seems by DVD Decrypter (supposedly) and I also had anti-region software resident...
To be honest, if this *IS* a new form of copy protection, I'll be a little more concerned about the fact that nobody knew about it before hand, then the fact that it is actually working!
