From SlashDot: http://slashdot.org/article.pl?sid=01/03/06/1954213&mode=thread

“Dr. David Touretzky has done it again, posting a 7-line 526-byte Perl VOB descrambler on his ever-growing Gallery of CSS Descramblers. ‘qrpff’ was written by MIT Student Information Processing Board members Keith Winstein and Marc Horowitz for a 6-hour seminar on ‘Decrypting DVD’ taught at MIT in January-February.”

Code takes awhile to read and understand but clearly shows the power of Perl.
