Leaping Brain's "Virtually Uncrackable" DRM is just an XOR with "RANDOM_STRING"

The wrapper script is GPL'd, so I copied it here:

http://dl.dropbox.com/u/15447644/brainplayer_py.txt

My modifications are on lines 553-556. The compiled app "fixes" the .mov file just long enough for it to be loaded into the player. If you have Leaping Brain's player installed (often branded with the content owner's name), the .mov files are in a hidden .media folder. On my Mac, they were in $HOME/Library/Application Support/LeapingBrain/catalog/$VIDEONAME/.media

Not sure how he could get in any trouble from it due to the license at the very top of the file he linked:

"# BrainPlayer is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License

I'm sure Leapfrog hated to put that GPL license on there but were likely forced to due to the VLC components they're using that are GPL/LGPL.
