Copy protection isn't intended to guard against computer savvy hackers. There's always going to be a way around any copy protection. It's intended to stop the "one-button" ripping programs that everyone can use. Or at least make the process time and labor intensive, or expensive.

Copy protection uses dummy chapters, patterns which cause the player to freeze and sometimes specific arithmetic commands which cause the copy processing to jump to a wrong destination on the disc. It's very sophisticated. Yes maybe the "printscreen" ploy works now because the studios are more concerned about producing disc for the market than they are about copy protection, especially since the cost of BD-R discs are still pretty prohibitive. Once it takes off and studios can retask their resources the copy protection will be more sophisticated than ever by utilizing more storage space. With DVD+-R being so inexpensive a hacker can make 5 "coasters" for every one DVD and still be ahead, depending on what value he places on his time. With most hackers, it's more the challenge than the movie.
