The whole DRM picture for CD's and DVD's just gets sillier and sillier. Have a look here - if you want to defeat DRM, all you really need is some tape:

Applying a piece of opaque tape to the outer edge of the disk renders the data track of the CD unreadable. A computer trying to play the CD will then skip to the music without accessing the bundled DRM technology.

The problem is not easily solved, either - there are tons of "legacy" players out there, and I can't see the industry being stupid enough to create a "day zero", after which no new CDs or DVDs will work on the older players. Not to mention the difficulty of getting the Linux community to care. Not to mention the fact that - in an international market - it just isn't that hard to get hardware from somewhere else (good luck convincing overseas vendors to avoid a money making opportunity).

Then there's the simpler issue - any noise in that direction would simply accelerate the move to downloadable content. Meanwhile, Gartner is proving that software isn't the only sector that they have a weak grasp on - check this bit of mutton-headedness out:

Gartner predicted that the music industry will start to lobby for legislation that requires computer makers to include DRM technology on their systems.

But the analyst advised that, instead of limiting what users can do with music they have already purchased, record labels should focus on tracking this use.

This would enable a "play-based" model where users are charged a fee based on how they consume music.

Yeah, "phone home" setups go down so well with people. Follow their advice on this one, and you'll have the kind of PR nightmare that Sony is dealing with.
