There is something informative in the hubbub to try to stamp out CSS (open source DVD player) which exposed the DVD decryption details. News reports consistently portrayed this as a move to provent pirate copies. This is not really true. Making bootleg copies of a DVD does not require decrypting anything, simply a sector by sector copy. Access to the decryption, however, enables access the streams (which actually would be necessary for 'fair use' access). Is that what they're really afraid of?
