Ignore UOP on the OSX dvd player

If you’ve been frustrated by the inability to skip past parts of DVDs on OSX the here is one solution. It’s a patch script that uses some binary hacking to remove the User Operation Prohibition locks from DVD playback software. Using UOP flags is a way to force users to watch trailers or warnings as part of the DVD experience. This script can patch Tiger, Leopard, and Snow Leopard systems. It also has the ability to generate diagnostic information for other installations that will lead to expanded support in the future.

    or you could just use VLC.

    I’m just sayin’.

    or windows….

    You’ve paid for the bloody DVD, and you still get punished for being honest by having to watch the video about NOT pirating, which I could deal with, but combining it with forced adverts takes the piss.

    Everytime you set the UOP flag, piratebay seeds another copy.

    Every time I see a UOP flag on a DVD, I increase my seeding bandwidth to spite the dvd publisher.

    Every time you’re forced to watch something via UOP flags on content you paid for, a Kitten and/or puppy dies.

    Thank you for saving these innocent creatures.

    we get it, MACs sucks, can we read about hacks now ?

    another thing that would be nice is if it could disable the blocker that blocks screen captures (command shift 3)

  12. P says:

    or, like other commenter stated, you could use VLC and happily skip around in the video and take screenshots all day

    This is the precise reason I copy DVDs. To remove the UOP and maybe the menus/extras altogether so I can just pop-n-play immediately…
