Well, new encryption probably isn't the issue as for things to be advertised as DVD they need to be compliant and any new encryption would have to work with the older DVD players.

I doubt there's any kind of program on the disc either - that program would have to be executed by some processor - either in the drive it's self or on the pc. I doubt the drive has a way to execute programming from the disc and if auto-run is turned off the pc shouldn't execute it.

Someday something like this may happen - I saw a blurb about putting rfid chips in the discs, I imagine it could be written into the drive firmware that if it sees a disc with an rfid tag that it wouldn't allow a copy or something.

Nothing I'm going to worry about for a while though . . .
