No Full HD Playback for 32-bit Vista
snafu109 writes "Pity the Vista user with a 32-bit CPU. Senior Program Manager Steve Riley announced today at Tech.Ed Australia that full HD content shall only be played at the full resolution where only signed drivers are used — only in the 64-bit version of Vista. From the article: '"Any next-generation high definition content will not play in x32 at all," said Riley. "This is a decision that the Media Player folks made because there are just too many ways right now for unsigned kernel mode code [to compromise content protection]. The media companies asked us to do this and said they don't want any of their high definition content to play in x32 at all, because of all of the unsigned malware that runs in kernel mode can get around content protection, so we had to do this."'"
Already on the way, even the cheapo $75 CPUs have 64-bit support now.
No, in the name of "Rights Management". Security is something completely different, and much less important (apparently)
Belief is the currency of delusion.
HD definition content is and will still be playable on any Windows computer with the proper hardware and software. However, HDCP protected content will not be playable in full definition unless the proper DRM requirements are met.
Linux already plays HD content. I have proof in my living room today.

Enjoy! I can do soooo much more with my myth box than a cable or sattelite provided pvr. I can store to DVD, I can watch from multiple networked locations, etc.
HDCP, the content-protection mechanism used for HD-DVD *and* Blu-ray, has been thoroughly cryptanalysed already by multiple groups (see http://en.wikipedia.org/wiki/HDCP#Cryptanalysis or do a google search).

And working devices to "erase" HDCP from a video stream have already been produced and sold, e.g. this one: http://www.engadget.com/2005/07/21/the-clicker-hd
The "smart" part about HDCP is that it allows content manufacturers to revoke keys, so that new discs won't play on hardware whose key has been compromised. However, it seems fairly unlikely that manufacturers will actually do this, given that they'll break the hardware of thousands or millions of users every time a key actually gets revoked! Furthermore, as the cryptanalysis shows, it'll be fairly easy to create new working keys, so it's an ineffective defense anyway.
Conclusion: HDCP is leaky as a sieve. My bet is that it won't be long before there's a hassle-free open-source program that will simply remove it from content transparently, just as libdvdcss does for DVDs right now.

> I can already here the meme coming up, "oh, 32-bit isn't enough for HD, you need 64-bit to do HD!".
Please quit misusing the term meme. I'm really tired of every concept, joke, or fad being called a meme. From dictionary.com:
meme
n : a cultural unit (an idea or value or pattern of behavior) that is passed from one generation to another by nongenetic means (as by imitation); "memes are the cultrual counterpart of genes"

You are forgetting one important point, sir. The premise that "Content" = "Media" is, to me, wrong. I buy the content, but that should not allow any restriction on the media. I believe it my right to use the content any way I choose, because I bought it.
Why should I have this right? Because our copyright system is based in the Constitution, and exists solely for the purpose of the public good, and solely for a limited amount of time.
And over there we have the labyrinth guards. One always lies, one always tells the truth, and one stabs people who ask t
I'm saying who will build and who will buy the more expensive 64-bit Vista MCEs?
My understanding is that there will be no price difference between 32-bit and 64-bit versions of the same SKU. So if you have a 64-bit processor, you would get the 64-bit version. There would no longer be any real reason to put a 32-bit OS on a machine with a 64-bit processor.
If you don't know where you are going, you will wind up somewhere else.
Well, your knowledge sucks then. The first HD-DVD player on the market runs redhat Linux, so there ALREADY IS a hd-dvd player for Linux.. just comes bundled with hardware.
