Nebo double-ROT13, viz http://www.cs.nmsu.edu/~joshagam/css/
[Not the DeCSS Source]

    Note: Under the DMCA, ROT13 is considered "use protection," and so
    the output of this program has been double-encrypted through ROT13
    so as to protect its output.  Replace the "decrypt - see note" in
    the command above with some means of decrypting double-ROT13 (also
    known as ROT26), in order to make the output usable.

Myslim, ze vetsina pravniku tenhle vtip nepochopi. Hlavne ze byli
schopni vymyslet DMCA... :-|
