Re: Fantastic Four: Rise of the Silver Surfer needs firmware updates as well....
Copy protection differences are one reason. But more commonly, it is the formatting of the software title. BD+ and BD-J are a couple of those formats. Since we are in the "early" stages of the format, nothing works together. I believe that this all comes down to the fact that there is no standard for Blu-ray. There's 1.0, in a couple days there will be 1.1, and then they have already announced 2.0. What? How about we just make all the discs work with all the players? It's not that hard of a concept to grasp. And it surely is not that hard to implement.
