HDCP is broken:

I don't know what problem that person was having but it's not related to some
form of new DRM on DVDs. The encryption on DVDs can never be changed. If it
were the millions of DVD players still out there in the world would be
rendered incompatible because, unlike Blu-Ray players, they cannot be field
upgraded. Thanks to this we can say that the DRM on DVDs is permanently and
irrevocably broken.
I understand that work on Blu-Ray continues. There has been some success but
also much still needs doing.
"Then again, who buys DVDs anymore? The optical disc format could just be
dead as it is."
Don't count it out yet: Since the DRM is permanently broken it's a way to get
DRM-free movies. :)
