Some 'Next-Gen' DVDs May Not Work With Vista
schnikies79 wrote to mention an article on the Times Online site, where they report that a 'substantial number' of Vista PCs will be unable to play HD-DVDs or Blu-ray discs, as a result of DRM requirements made by the operating system. From the article: "Dave Marsh, the lead program manager for video at Microsoft, said that if the PC used a digital connection to link with the monitor or television, then it would require the highest level of content protection, known as HDCP, to play the discs. If it did not have such protection, Vista would shut down the signal, he said."
For anyone who's been following the recent debates about Vista, this is already old news. But now the mainstream seems to be picking up on it.
What the article doesn't mention is that, probably precisely for this reason, there seems to be an agreement between Sony and Microsoft that HDCP protection won't actually be required by Blu-Ray discs until at least 2010, maybe even 2012. Remember, it's the disc that actually needs to require it, the operating system only provides this as an option.
That doesn't make the system anymore pleasing though. I wonder how far Microsoft will actually get with it. Customers do seem to get upset with this, and it wouldn't be the first time Microsoft has had to make "concessions" because of public criticism.
Peter Gutmann's paper on Vista's content protection is really recommended reading, even if it's a bit polemic. And nothing beats Microsoft's own document, written by the same guy that was interviewed for Times Online.
"Dave Marsh, the lead program manager for video at Microsoft, said that if the PC used a digital connection to link with the monitor or television, then it would require the highest level of content protection, known as HDCP, to play the discs. If it did not have such protection, Vista would shut down the signal, he said. "
The next-gen DVD's will work with Vista, but you need to have HDCP compatible hardware if the HD DVD has the HDCP flag.
Plus, AFAIK, there are 0 HD DVD's that have this flag enabled. Rumored it will not be activated on any disc before 2010, if at all.
