Derek Wyatt let's slip some uncomfortable truths for the scions of music and movies: DRM is impractical, and is ultimately a waste of time and resources. We actually went through this years ago, with PC Games and locked floppy disks. That failed too, for the same reasons. There are two really good points he made. One:

The problem is that digital rights management relies on locking content away, and as long as we have general purpose computers capable of running whatever code someone cares to write then there will always be ways around those content locks.

That's not about to change, either. With the rise of open source systems, you're not going to see full lockdown. More relevant are the social issues. To wit:

My daughter is fifteen and cares about copyright. She knows that I rely on it in order to get paid for what I write. But she does not care for copy protection when it stands in her way, and will happily rid DVDs or strip DRM from downloaded music in order to use material flexibly - and fairly.

She buys CDs and DVDs and books, and respects copyright for what it is, a limited monopoly on certain forms of exploitation and use. She does not believe that it is an absolute property right, and she knows perfectly well that ripping a CD is not theft in the way that stealing a disc from a shop is.

That's the major problem for the RIAA and the MPAA: their customers simply don't believe what they say. The vast majority of "theft" is simply fair use. The moguls know it, and we know it. What's going on now is simply denial on their part.
