Yeah, same here my friend!
I'm tryin' to copy the first disc and just can't seem to do it with anything! Looks like this might be some new protection we haven't seen yet?!
I've tried using DVD Decrypter 126.96.36.199 (probably a bit too dated for the newer protections!) and DVD Shrink and neither of them could do it. When looking at the files on the DVD they do seem very different from normal DVD's, there are many files on the disc (more so than usual).
I've got a feeling that the disc is packed out (to make the disc 'appear' a certain size) with bad sectors which the copiers seem to be overlooking. I'm trying to copy it with an ISO copier I have on the Xbox and will let you know how I get on...
Good luck fellas!
