Re: Show details - Re: NVIDIA Decoder Problems

Well I would like to see it, I really would. I even went so far as to
contact Nvidia. The answer was note the quotes "it is not recommended for
any hardware outside of the supported list", with a link to a support site,
so I am curious as to what the supported list is and oddly enough the link
went right back to where I was at the very start on their web page,, which I
gave the link to before.

So my next challenge was I took a bare image with just the Sonic MPEG decoder
and the ATI / Cyberlink Decoder. I ran a DVD under media center and media
player, no problems. Ran it with debug symbols everything was perfect.

Then I installed the Nvidia decoder, it did install, but the panel did not
come up under media center, but media did show the applet their, even though
the diagostics and controls did not run. Use the Microsoft XP decoder check
to set it as default. I played the same DVD, with debugger capture
information and oddly enough I did not get any symbol information whatsoever
from the Nvidia DVD driver. At this point Windows Media player no longer
played DVDs, I just got a lot of junk, but I did see the Nvidia applet icon
running, but the media center did run the DVD and did not show the Nvidia
applet running, ddk stream debugger showed the decoder data was coming
through the cyberlink decoder. I have 400+ MB of data stream decoder
information if youwant it, I can send it to you. At this point, I removed
the Nvidia driver completely, verified this with the DDK tools as well as
Winternals tools as well as the DVD backup image I took of the install prior
to installing the Nvidia software. Ran the same DVD, and miracles of
miracles, media player now worked, media center still worked and the data
stream capture show identical decode information with the cyberlink codec.

I did the same experiment, but did not reboot the machine but just removed
the Nvidia decoder and the media center started the dvd right at where it
started even though there was not a Nvidia dvd decoder present in the
machine. Which again proves it did not even use it when it was there. All
the driver diagostics showed the nvidia drivers were not active, and the
decoder data streams did not show any nvidia decoder data. So where is nvidia
in this equation?

Then I did the same experiment with the Nvidia blackbird tuner and installed
the same decoders, this time with nvidia drivers, captured the same stream
data. This time media center did come up with the controls for the nvidia
decoder and media player worked correctly throughout. I did install the
third party cyberlink decoder, not the ATI version. This failed to work with
Media center similar to how the nvidia decoder did not work with the ATI
card. I do not have an explanation for it, but there is a patch on
cyberlink's website for the decoder, I tried it, but it did not help either.
When I reviewed the stream data with the nvidia decoder in use, I oddly
enough saw that the data stream WAS decoded by nvidia decoder.

So once again, you tell me how I am wrong here. Please document a procedure
other than "it works for me". I spent six hours on this, documented the
steps on the way, verified the hardware and software and I still get the same
conclusion.

Again tell me in fully documented many with logs how you achieve this.
Certainly Nvidia doesn't seem to want customers to user their decoder on
non-nvidia hardware. By the way, I am sending the same information to ATI,
Nvidia and Cyberlink, and I curious as to what response I get from other
engineers.

Also I know what drivers I used, ATI Catalyst 5.5 MCE, ATI / Cyberlink DVD
Decoder 6.0.0.1311, Nvidia DVD Decoder 4.67.0, Nvidia gforce 71.84, Nvidia
TV 1.20.45.
