Cablevision Seeks to Deploy Network DVR

Cablevision Services has been laying the groundwork to deploy a network-based digital video recording system that would record your favorite television show inside the cable network, and deliver them upon demand ... in contrast to the existing local storage model. 

In response, Twentieth Century Fox Film, Universal City Studios, Paramount Pictures, Disney Enterprises, CBS, ABC, NBC, and others have banded together to sue Cablevision, claiming that such technology would violate copyright laws.  A New York federal judge has ruled that this favor of the TV networks and Hollywood studios, but Cablevision is considering appeal.

It seems like only a matter of time before such Video on Demand services become available, as long as providers like Cablevision can navigate the legal pitfalls.
