New unbrakable copy protection scheme
JVC has announced that it will use a CDROM copy protection scheme based on the collaboration between itself and a Japenese company Hudsonsoft. The scheme called the 'Root', records an encryption key when a CDROM is created in such a way that an error is generated when any attempt is made to playback software from copied disks.
It will be built into CDRWs so that copying to CD-R/RWs cannot circumvent it. The technology prevents encryption keys being read when copied disks are played back, and JVC hopes to sell mastering units incorporating the new technology to other manufacturers. The same technique can also be used to prevent copying of DVDs to any other media.

Oh geez... why does this sound so much like the original "unbreakable DVD crypto." Geez... *sigh* But if you have "both sides" of an encrypted conversation (including the keys), chances are you can break it given enough time and motivation (and, well, given sufficient knowledge/understanding). And, still, they have reverse-compatibility to worry about to boot...
Until someone takes something like Divx (?) and "holds all the keys" (ie. you dial-in or connect across a network or something before you can get "authorization" to view something), I can't see how they're going to protect these things.
And yes, I know I'm probably not explaining my point terribly well right now... my apologies.
