    I inserted my DVD, opened disk utility and made a disc copy of the DVD. Everything went smooth so i opened the dmg file. The file got extracted nicely, i took the real DVD out of my computer again.
    Then i started DVD player and played the disc copy but after six seconds i got an error: Error -70025. It had something to do with a problem with the authentication code.

    Does anyone have had this same problem en is there anyone who can help me?

    Looks like some sort of protection. I'm guessing that you can't make a perfect copy for playing unless your copying program (in this case diskutility) reads every block from the disk. They maker of the disk may have implemented copy-protection, and you need either: a ripper that defeats code checking (MactheRipper is good) or a program that will make blovk for block copies, even the unusually sectors. I've heard of some utilities doing this to copy gaming console disks like the PlayStation platform.

    Specifically, what kind of DVD are you trying to copy? Commercial? Burned?
