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."

You do know that Apple and OSX will have exact same DRM requirements as Vista to play HD-DVD/B-R content that have the HDCP flag enabled. That this is a requirement in this particular media standard that any player (including standalone non-computer based players) will need to follow to be able to play it (outside of a cracked version for Linux maybe). So following your logic, OSX is collapsing as well, or will not be able to play these discs at all.

I'm actually hoping the technology advances to the point where it can enforce the letter of the license *EXACTLY* so people wake up to how oppressive the various license agreements (both the Windows one and the ones for the music and movie media) are.
If people had any idea how bad it was (can't show a DVD on a college dorm shared TV because that's a public display that the DVD doesn't give you a license for ; can't install windows on VMs for testing without paying more ; etc) - they'd object much more strongly.
The current situation where it's easy to break Windows and DVD licenses just advantages unethical companies and people and hurts the ones that attempt to be law abiding.

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. [arstechnica.com] 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 [auckland.ac.nz] on Vista's content protection is really recommended reading, even if it's a bit polemic. And nothing beats Microsoft's own document [microsoft.com], written by the same guy that was interviewed for Times Online.

What the article says is that there is an agreement not to implement the Image Constraint Token (ICT) yet. This is a token that forces a downgrade of analog signals. This is why the Xbox 360 can have a HD-DVD add-on without a HDMI port.
This does not apply to digital output. Even if the discs don't have this set, you still need HDCP if you want to get a digital link to the monitor.
So, if you are using VGA to the monitor you are ok for the moment, but stuffed if you are using DVI or HDMI without HDCP.
Of course, this understanding comes from reading the AACS licence agreement (freely available from the aacsla website). Unfortunately, this agreement is as clear as mud, so I may be wrong.

What he DID say according to TFA [timesonline.co.uk] was "At the moment HD DVD and Blu-ray Discs certainly require such protection."
I don't know why he would be misinformed, or why, given the importance of this issue to Microsoft, he would be less than careful about what he said.
Most likely, current disks really don't play, because of some complexity in the interaction between Vista's DRM software and hardware that results in an illogical and unintended consequence.
If current disks will play, why on earth wouldn't he have taken great pains to say so and to stress the point.

However, even if the disc doesn't have this set, you still can't get unencrypted digital output (such as DVI without HDCP). Unencrypted digital output is simply not one of the allowed output formats of AACS encrypted media.
Thus, you will be able to currently play discs at full resolution over VGA, but (without new HDCP capable hardware) it simply won't work over DVI.

What people are whining and complaining about is that Microsoft is actually following a standard. These same people are the ones that complain when Microsoft doesn't follow other standards like CSS2. It's just that the standard they are following happens to be one that implements DRM, and now they're going on about how "Oh, gee, they fully-implemented the standard!"
*sigh*
Here's the answer: don't buy HD-DVDs and BDs that require HDCP. Duh. Vote with your feet. If enough people really put their money where their mouth is (as opposed to what they normally do, which is just paying lip-service), and truly advocated that others do the same, it will make a difference. Sadly, most people are so weak in their convictions that when their favorite movie comes out requiring HDCP, they will just buy it no matter what.

You mean Peter Gutmann was RIGHT? (Score:4, Insightful)
I have to admit that even though Peter Gutmann is a respected computer security expert while I know virtually nothing about Vista, I was inclined to think his analysis [auckland.ac.nz] just had to be wrong. He had to be misunderstanding something, or positing a hypothetical situation that would never arise with real-world commercial gear, or something like that. Microsoft simply couldn't be that stupid.
Now it turns out that he's right, and that presumably-unintended but not-unforeseeable consequences of Vista's DRM scheme will prevent it from being used in the one way you'd think Microsoft would most want it to be used. It is precisely the enthusiastic with money to devote to their video hobby who are likely to be the early adopters of PCs as home video platforms.
Microsoft is coming perilously close to providing the platform that secures protected perfectly content by preventing _anyone_ from viewing it.

It seems MS is being bashed for following the requirements being set forth by the media producers. Whereas a number of MS practices may be less than honorable, in this case from what I see they are simply holding to the requirements of the format standard.
All in all I think the media companies like Sony have been given enough DRM rope and are within a year or two of effectively fashioning themselves a noose from it, but that's just MHO on the topic.
Re:OK, for us who arent *nix experts. (Score:5, Interesting)
The problem, though, is that this situation did not need to be this way -- Microsoft could have teamed up with the electronics industry to say, effectively, "go to H*ll" to the content producers. The content producers would then have had to choose between (A) not releasing HD content or (B) releasing a non-DRM'd version. Their claim is that they would choose (A). But, they're full of crap -- doing so would deny them a new revenue stream in the face of increased competitive pressures. If the market didn't force them to switch, their stockholders would have.

This is one of a long list of reasons that I won't be upgrading to Vista or HD-DVD/BluRay in the forseeable future. The sad thing for all of the companies involved is that I usually am an early adopter of technology.
I was one of the first people I knew to own a Tivo, DVD-player and an HD set (okay, I didn't own the set but I pressured my dad into buying one and he was really happy with it). I bought a copy of XP pretty much as soon as it was available. Last count, I owned nearly 500 DVDs.
And that's about as far as my relationship with these companies go. I--a legitimate, paying customer--am unwilling to be inconvenienced one single second, or pay a single extra dollar, to be treated like a criminal. I simply won't do it. So I'll continue buying DVDs until they stop manufacturing them, hopefully by which point this whole fiasco will have blown over.
