My concern is less about what Vista will require directly, since I can choose to keep XP installed on the HTPC or use another OS. My problem is that MS is requiring hardware manufacturers to change their products to enable what could be a simple function such as HD content playback.
Unless you've got some links to info that I've never seen, that's not MS, that's the studios that produce HD content.
As I understand the issues, your choices are no DRM, and no support for HD DVD/Blu-Ray in full resolution (if the studios turn the flags on) or you get DRM.
I don't like it, but these standards are being forced on MS (and presumably Apple) by the MPAA.
Respectfully, that is BS. M$ is attempting to control the HDCP channel. The MPAA can't force anything. Here is the link to the article with all of the scary information. Pleas read it in it's entirety.

So you have a way to play HD DVD and Blu-Ray (without using some hack that probably breaks the laws in the U.S.A.) at full resolution?
If so, please enumerate the ways you can play back Blu-Ray and HD-DVD on those platforms at full resolution over non-hdcp compliant hardware (and for the sake of this discussion, let's assume that the bit that forces the downconversion of high def content has been turned on).
If you actually think that the studios, which REQUIRE ALL HD-DVD and Blu-Ray players to downgrade video over analog outputs IF a certain bit is turned on (it currently is not because it would obsolete too many TVs), then you're naive.
Most of this article is dealt with
here.
My guess is if you were to go buy an HD drive and hook it up right now, it'd work, because the content protecition flags are turned off on most, if not all, released HD content.
