It's not working for me. Last Bluray I played was Avatar, installed Ubuntu, obtained the file, entered the hex over my DRL files but still the same error. Tried Rambo 4 just incase but nothing either.
Guess I'll have to wait for another solution.
I bought the PS3 second hand with a duff laser, maybe the previous owner played a movie with a higher MKB than Avatar. I guess I'm out of luck.
