Film Industry Tries Its Own DRM

The DVD industry, battling its own hacking/DRM issues, has released a new technology for preventing unauthorized copying of Blu-Ray or HD-DVD discs, reports the Wall Street Journal:

[O]nce a password is compromised and posted on the Web, the industry answers by changing the way in which its new DVD titles are made. Anyone who pops one of the new discs into their personal computer without installing a software upgrade will find that it destroys the computer's ability to play any high-definition DVD at all. To restore the computer's ability to play them again, the owner is forced to download new software from the Web -- software with a new password that hackers haven't yet discovered. The old password, or key, has been revoked.

This is called "key revocation", and it's frustrating innocent consumers simply because the moment a hacker uploads a password to the web, ALL users of that DVD are affected and must download new software with the new password in order to play ANY of their DVDs.

Pretty draconian. And a real turn-off.
