    Guys, it seems that nobody will be able to make his own movies with Vista
    because M$ thinks that all devices and drivers should be certified to allow
    them working.

    Also take a look at this one:

    "Decreased Playback Quality
    --------------------------

    Alongside the all-or-nothing approach of disabling output, Vista requires
    that
    any interface that provides high-quality output degrade the signal quality
    that passes through it if premium content is present. This is done through
    a
    "constrictor" that downgrades the signal to a much lower-quality one, then
    up-
    scales it again back to the original spec, but with a significant loss in
    quality. So if you're using an expensive new LCD display fed from a high-
    quality DVI signal on your video card and there's protected content present,
    the picture you're going to see will be, as the spec puts it, "slightly
    fuzzy", a bit like a 10-year-old CRT monitor that you picked up for $2 at a
    yard sale [Note F]. In fact the specification specifically still allows for
    old VGA analog outputs, but even that's only because disallowing them would
    upset too many existing owners of analog monitors. In the future even
    analog
    VGA output will probably have to be disabled. The only thing that seems to
    be
    explicitly allowed is the extremely low-quality TV-out, provided that
    Macrovision is applied to it.

    The same deliberate degrading of playback quality applies to audio, with the
    audio being downgraded to sound (from the spec) "fuzzy with less detail"
    [Note G]."


    Sounds scary. I'm wondering if anybody really wants to switch to Vista :)
    I'm talking not only about digital video or audio, but medicine where the
    quality of images and signals can be deathly dangerous, etc. BG created a
    very nice system for the whole digital world :) You will not be able to
    control your own machine and have to live with NT/W2000 or XP without
    service packs because they can apply any critical service pack automatically
    through the INternet to "improve" these systems and turn all your critical
    devices off. Or move to Linux.

    How do you like that?

  2. The same will happen to Audio in due course - eventually, Vista won't
    play audio unless the all-digital encrypted "secure audio path" is
    implemented.

    To be fair, it's worth qualifying that all this jiggery-pokery is
    related to rights managed (DRM) content, not any old standard content.

    Brave new world indeed.

  4. OSX is a layer on top of BSD Unix, which is broadly open-source (the
    source code may be checked and modified / recompiled)

    As a result, the OS internals may be inspected with the correct
    in-memory deubgging tools, making DRM as implemented in windows
    broadly unworkable (because the OS isn't locked down, the unprotected
    data may be acquired at some point) - this is known as "curcumvention"

    Without investment by Apple to modify BSD architecture to provide a
    secure digital path for protected content, there are 2 consequences I
    can think of :

    (1) Hard for Apple to definitely keep protected content 100% locked
    down, to the satisfaction of the pigopolists.

    (2) Unwillingness for MS to release DRM component to Flip4Mac, so Mac
    currently can't get DRMv2 content playback for windows media content

    I'm not sure what if any effect the availability of the TPM chip would
    have on that scenario - at present it's intended to prevent OSX being
    run on non-apple hardware AFAIK, but it could likely be used in any
    secure digital path implementation - see
