New Blu-ray discs with BD+ DRM failing to play on some devices
 

One upon a time in a galaxy far, far away, most consumer products were expected to work "off the shelf" and didn't require frequent "firmware updates" to do so. With the new generation of HD DVD and Blu-ray video players, however, this is the norm: firmware updates are to be expected because the players are constantly evolving and are built around a DRM scheme (AACS) that can be "updated" in the event that a hack is found. Blu-ray goes one step further and adds another layer of anti-copy technology known as BD+, but the latter is only now starting to be used. As it turns out, it appears that it's causing problems for many honest customers.
