From Tech Crunch:
The DRM camp is now saying that copying is good—to a degree. The upcoming DVD release on November 20 of Live Free or Die Hard will be the first to allow digital copies to your PC and one other USB-attached device. That’s two copies for the price of one DVD. The folks at Fox are calling this a Fox Digital Copy, and plan to roll it out with future DVDs as well. The catch: any device you put it on needs to be compatible with Microsoft’s PlayforSure DRM technology. That excludes all iPods, Sony PSPs, and even Zunes.
