Jebus: HD DVD works just fine on XP. So does Blu-Ray, for that matter.
The DRM system in Vista is only active if you playback protected content. And as a rule of thumb, everyone concerned about DRM should stay away from any protected content anyway, so i don't see the problem here.
In Windows, staying away from DRM is as hard as staying away from the Internet Explorer.
That's pure BS. How can you say that? Where do you encounter so much DRM'ed stuff in Windows compared to other operating systems?
iTunes is probably the biggest reason as to why DRM is so spread around as it is today, and hey, it's not a Microsoft product (but it is available on a Microsoft OS however).
The DRM system in Vista is only active IF YOU CHOOSE TO USE PROTECTED CONTENT. You have the choice. On Linux however, you don't even have that choice!
And no, you can't legally watch HD-DVD (or even DVDs) in Linux.

How do I get KS working in Vista? With a Realtek ALC882, no devices are listed for KS output in Foobar - only DS.
Thats a nice thought but 99% of consumers aren't aware of DRM. So is it fair to sell things to an unaware public? And to those that are aware, how can you be sure if DRM is not part of what you are purchasing? i.e. Sony rootkit scandal. No offense but it almost sounds like you work for MS.
Contrary to popular belief, the kmixer of XP and 2k doesn't change a thing when you move the wave volume slider to the max. DTS encoded wave files can be played through WaveOut/DSound and through the kernel mixer without any loss.And I should know, I've developed a driver for the C-Media 8738/8768 which just can do that stunt.
The mixing engine of Vista works with 32bit float samples, so there's actually some information lost in the conversion. But there is a so called "exclusive mode" which is available through the WASAPI. It should give you bitperfect output, albeit I haven't seen software which actually support it (yet).
No. Windows has a mixer. The mixer has to take what can potentially be several sources and mix them. So no one can be at full volume, even if it is the only thing playing, because then if the system beeps for example you either have the possibiliy of clipping or you have to reduce the volume of what is playing at the same time. Not unreasonably, windows doesn't do this.
You have to download the KS plugin from the Optional Components link at Foobar2000.com
I see you are really knowledgeable, sire! May I suggest you just give up posting on this thread and move on to a topic you actually know about?http://www.intervideo.com/jsp/LinDVD.jsp
Kinda makes you think, doesn't it.
KMixer issue resolvedHere's an update to the KMixer issue.Some of the design goals for the KMixer that affects this issue are:1) Create a standard interface to the audio device2) Handle multiple asynchronous streams of audio3) Handle streams of different sampling rates4) Efficient, low CPU usage (keep data streams moving, even on slower systems)5) Volume controlIn order to meet these goals, the KMixer can not guarantee bit perfect playback. Hence it does not support non-PCM streams. The DTS CD (masquerading as a PCM stream) is corrupted in the process. DVD and CD players don't need to meet the above requirements, so they simply pass the stream along. DTS really should have standardized their format. Regardless, the bit manipulation occurs because of volume control.Since most PCM data is 16 bits, on MMX systems the KMixer uses 16 bit math to take advantage of the SIMD parallelism of MMX. 15 bits are used for multiplication and 1 bit for sign. This means that the KMixer can not represent an amplitude of 1.0. The best it can do is 7FFF/8000. So on MMX systems, when the volume is set to 0dB attenuation, KMixer still attenuates the signal slightly - so the bits are changed.On non-MMX systems, the KMixer uses floating point math to handle volume. This results in higher CPU usage, but allows the KMixer to reach an amplitude of 1.0. The floating point numbers are then converted back to integers (because that's what the sound card is connected with) and ends up dithering the stream in the process.When bit perfect playback is necessary, Kernel Streaming is recommended.Essentially, it comes down to the following:1) The KMixer does not support non-PCM streams (which the DTS CDs are)2) A 1/8000 volume attenuation is extremely small. Can anyone hear really hear it? Refer back to KikeG's measured ratings:http://www.avsforum.com/avs-vb/show...886#post2493886I recommend continuing to use Kernel Streaming for your DTS CDs. For PCM data, it is not necessary.
Ahh, so either I am lying, or I am in a delusional state of mind . Yeah, that must be it.Seriously, try it yourself if you don't believe me. A cmedia card with digital outputs costs ~15 USD.
So what happens if a second application tries to play sound? Is there clipping, or is volume reduced?
Yes and when they are mixed together, is the volume of the first reduced or is there sometimes clipping? One of these would have to hold if you are right.

The only reason Intervideo got a CSS license at all for LinDVD was that they agreed that they would only develop it for the OEM market.
