ozmanjusri's Journal: Vista DRM actually works.

The Electronic Frontier Foundation is investigating an incident when Microsoft Vista Media Center computers blocked the recording of some NBC television shows.

When Vista Media Center users tried to record American Gladiator or Medium, a prompt informed them that the copyright holder prohibited recording. It seems that Vista has honoured NBC Universal's broadcast flag, despite a court ruling that software and hardware makers are not required to do so.

It remains to be seen whether this is an example of Vista being defective by design, or implementation.
