All copy protections, even the hardware based types with dongles and keys, have in time been broken. Every single one. That is why they are of no value in preventing piracy. Real pirates, the folks who dupe and distribute and make money and thereby take money out of the pockets of the producers, those pirates always find ways to break protections. Even BD+ will be circumvented. All the various DRMs do is annoy legit users and prevent them from protecting their investments by making backups. A little additional money flows in as a result of customers having to replace damaged goods, but no reduction in real piracy occurs. In fact, I’d bet that in addition to the vast sums wasted on DRM by producers they actually lose some business because potential customers that in the past would have been exposed to products through “piracy” and then purchased them legit cannot do so easily any more. As for the original question, will DVR kill the DVD? Not a chance. Despite Microsoft’s hope of a media-less distribution system where everything is on demand and broadband downloaded, people just like having something to show for their purchases. And people don’t trust big business to manage their entertainment, so the potential DRM headaches, and the threats of having auto deleting content and forced commercial viewing are likely to scare enough users away that MS and other providers with the same greedy dreams will be left holding the bag. Hopefully anyway. So whether it’s a DVD, BD, or HD disc, so form of physical media is likely to survive long into the future.
