No Vista default Graphics Hardware Acceleration?

I noted today that the Release notes for the new NVIDIA 100.59 driver
release state under Video Performance that the current default VISTA MPEG2
decoder does not take advantage of hardware acceleration.
From many posts and from CPU utilization data utilizing the same recorded MC
file on XP and on Vista on my dual boot system this appears to be true.
It also seems to be true that the NVIDIA Decoder on Vista does not take
advantage of DX9 hardware acceleration.
Does anyone have any confirmation of this from MS and if so is there a plan
to supply a patch in the near future.?

There are many issues with nVidia's drivers at present - they were not
feature-complete and stable at the time of Vista's release (don't know why -
they certainly had plenty of time). Look for links on digg.com or
arstechnica.com or extremetech.com. I would expect things would get better
in the next month or two, as they claim they're working hard on them. I'd
suggest looking for new versions on their web site every day or three...

I interpreted the release note statement to not be a function of the graphic
cards vendor or its Vista drivers but as an graphics card independent issue
with the MS provided MPEG2 Decoder in VISTA since on my dual boot system
with Intel graphics Vista uses a lot more CPU power then XP uses when
playing back the same recorded TV program using MP 11.

this is true from what I can tell Microsoft has made no indications that
they will ever support hardware acceleration of Mpeg2 on they're decoder.
If you ask me that would be dumb. Second point is that NVIDIA instead of
whining about it should release their version of purevideo decoder with the
hardware acceleration included... again NVIDIA has no current plans to do so
according to they're answer base.

And how did you do that? I tried installing the current version of PrueVideo
in Vista Ultimate and the installation stopped with a incompatability message.

I am running RC2 for testing only and I may have installed the .223 decoder
releae using XP compatibility mode I don't really remember. Maybe that is
why it says it is using hardware acceleration.
Also if you do want to use a different decoder in Vista you will need to use
the utility at the following link;

Since the XP decoder utility while appearing to work does not since Vista
gets its preferred decoder from a different registry location then XP does.

As near as I can see, you don't want to use the NVidia decoder in Vista. I've
observed that CPU utilization runs about 30-60% with the built-in Vista
decoder and pretty much 100% with PureVideo - hardware enabled or not.

I'm currently running Vista MCE with a 3GHz, 1.5Gb, GeFrorce 7600GT system
utilizing a Hauppauge 500 dual tuner (connected to a pair of DirecTV HD
boxes) and VBox Cat's Eye dual PCIe OTA HD tuners. This this setup is running
great - perfect in fact - with the built-in decoder. I can record 4 programs
and be watching a 5th without a single glitch. Not bad.

I also might mention that Vista MCE has many improvements over prevoius
versions, well worth the upgade.
