Cablevision's digital video recorder has the movie studios and television networks up in arms. ABC, CBS, Fox, NBC, Disney, Paramount, and Universal have sued over the nDVR, or network DVR, claiming copyright infringement. The nDVR stores up to 80 hours of programming on a remote server. Program it to record your favorite stuff in perpetuity and you have, in effect, a limited version of video on demand. Since the disc drive is not in your rack, you can operate it just using an dDVR-enabled cable box. Cablevision says the suit is "without merit." Analysts say the suit was expected, and if Cablevision prevails, cable ops will be able to deploy the dDVR on a larger scale and save big bucks in the process, both for consumers and themselves.
