Registry settings for Nvidia decoders

[Commodore 64]

Here is a great explanation of the nV codecs and what different settings there are , and which ones you should use:

I know this post is about a year old, but I would like to know if anybody has solved this problem?

Purevideo works great for dvd's, but doesn't start when I'm watching tv.
I really would like to get it up and running. Mostly so that my cpu doen't have to run at about 90% all the time.

Any info would be appreciated.

I had the same symptom, where I set NVidia Audio/Decoder Decoder in configuration, but it wasnt being used when viewing TV.

Resolved the issue by going into Settings > TV > Audio & Video Decoder options within MP, and setting it there.

Upon MP restart, NVidia's Decoder tray icon comes up as expected.

Be aware that sometimes the tray icon doesn't appear but the nvideo codec *is* still being used.
Try GraphEdit and connecting to remote graph.
Or - if you use ffdshow - you can click its tray icon and see the whole graph stack.
As to why the icon doesn't always appear and what that means I can't say...

About DVD versus TV. If TV is interlaced and you are 'hiqual' deinterlacing then that can add a blur/sheen to things - using simple BOB deinterlacing on a CRT is cheap and just great for TV.

If you want to see a lot of more options in nvidia-configuration, use the following tweak:

------

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Filters\Video]
"EnablePropPage"=dword:00000001
"PureVideoPropPage"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Filters\Audio]
"EnablePropPage"=dword:00000001

Do I "need" to do this if I am using NVIDIA PureVideo?

Thanks.

Other than that I have a decent picture in MediaPortal with no interlacing problems (which I have problems with in Meedio).

Where is this free online tool?

Good explanation and download link, i found most improvement reducing the motion blur setting stopped a kind of ghosting/blurring and made the picture as good as a regular tv tuner in my opinion.
