An anonymous reader writes "In the last few weeks the first HD-DVD and Blu-Ray drives for PCs have slowly trickled onto the market. Up to now, it has not been clear what system requirements you need to actually be able to play HD-DVD and Blu-Ray discs. The operating system was the main cause of concern; many rumors cropped up that the new generation of video discs would not work under Windows XP. Hardware.Info put the question to Cyberlink, the company behind Power DVD, if the lack of a protected videopath in Windows XP would make it impossible to enable HD-DVD or Blu-Ray playback. They have answered the questions, and provide a complete checklist of what you need to play Blu-Ray and HD-DVD movies in HD resolutions on your home PC."

You mean like DVD was dropped? Nope, once they commit billions to pushing a format that have to follow through. At least once it hits a critical mass. If the crack doesn't appear until after millions of players are fielded and thousands of titles are released they are stuck.
Since Vista dropped the requirement for TPCM we have all known the next gen DVD formats were going to get cracked. As soon as a software based player is available it is toast. And I'll tell ya something else. Mplayer won't need a dual core CPU and a 256MB video card for playback either.
Regular DVDs could be played back with a 1X DVD drive, a Pentium 90 and a video card with hardware scaling and color space conversion (i.e. xv support). A little back of the envelope math tells me a fast single core Intel or AMD cpu is more than enough. If your video card can do scaled video and colorspace on 1920x1080 windows you should be in the ballpark. If you have XvMC support you should be golden. HD video isn't THAT many more bits or pixels per second, despite what the marketing would have you believe.
Besides, I still don't understand your thinking. If it isn't cracked I ain't buying in. Didn't buy DVD until DVD Jon make it usable. So if this stuff ain't cracked it can all rot in hell for all I care.

Ther's a LOT more going on with these formats than just playing back a single moderate data rate file! Look at the above, and you can see why multiple threads + GPU decoder and rendering asssist are extremely helpful.

Nice features to have, but most of us will only be watching the movie. One HD video stream and one audio, either decoded ijn software or passed out on an optical plug. And do the math on the movie itself. Assume a dual layer BD-ROM (by the time a crack appears these will actually be shipping in quantity) with a single movie. That gives you 50GB of data for a two hour movie. Compare to a DVD with 9

I gather you haven't seen any of the IME (In Movie Experience) titles. For example, on Bourne Supremacy, on the fly you can have a video commentary track, where the director or producer will pop up as a picture-in-picture to give a face to the narration. Lots of very cool things along these lines will be coming in later titles, and its stuff you'd want to be able to access. And we're talking real-world titles - there are clearly the bits available to do it.
Also, HD DVD absoutely mixes multiple audo sources in real-time, and this is used in real titles. They were required to be premixed on DVD, but not on HD DVD. This is a good thing, since you don't have to waste bits on doing the base audio when doing commentary tracks. This is also why audio decoding is moving out of recievers into the players, and the players output mixed PCM over HDMI as the optimum output mode.
You're dramatically underestimating the load of rich media playback, and overestimating the load of decryption. And I'm not aware of any software players that'll be doing any sort of reencryption in software, or why that would be needed.
I imagine free players like VLC will eventually support playback of non-AACS HD DVD discs. But they'll have similar decoder requirements. We're definitely talking about using GPU compositing, GPU codec decode assist, etcetera.
And we're not even talking about Blu-ray, which has higher max codec complexity, plus it has to run a Java VM and another encryption layer...

Why would it be a good thing?
Fact: DVD is near the end of its life for a high quality movie format. Disney titles for the kids? Another ten years, just like VHS is still clinging to life if that niche. A format to drive a 50" HD monitor? No.
Fact: Any new format will have all the DRM the industry thinks it can get away with.
Fact: The original plan was for Vista to be a TPCM only horror, and for HD content to only be playable on PCs with TPCM (ie. Vista and OS X on Intel). Hollywood had banked everything on that and was betrayed. (Nobody ever wins in a 'partnership' with Microsoft.)
Fact: If either/both of these new formats catch on they will be good enough to last 10-20 years, like DVD's eventual lifespan will probably end up and about like VHS's reign.
Fact: If both fail, by the time Hollywood is ready to try again we might not be lucky enough to get something so crackable.
Fact: If Hollywood has TPCM it is possible they might actually design something that can't be cracked. Or at least not cracked effortlessly, as DVDs are now. Microsoft's failure with Vista is our opportunity, we should seize it.

There is a technology called ICT (Image Constraint Token) that content publishers could turn on (but haven't) that'd reduce your output resolution to 940x540 if using a non HDCP output. But given how many players and sets there are out there that don't support it, all the released HD DVD titles don't use this, and will allow you to use every pixel of your current display.

Yes, and even those you buy yourself might have HDCP, but they won't have it switched on. However, many OEMs 'in the know' like HP, do. Sounds like lock-in to me.
The purchase of a HD-DVD or Blu-Ray player will therefore have no added value to a normal DVD player without HDCP.
