Speaking last week at the Digital Home Developers Conference, Brad Hunt, the executive vice president and chief technology officer for the MPAA, conceded that many people are frustrated at having to buy multiple copies of the same content to use on different devices and that this is driving them to piracy.

“I understand that if we frustrate the consumer, they will simply pirate the content,” he said. “The issue we face today is that consumers are buying content that uses specific DRM and that, in turn, is gradually creating a world of separate DRM systems.”
