this may be a noob question, but im new to PureVid and wont to make shur ->

The Vid playback Features in the new Nvidia COntrol panel on the 91.31 driver settings(such as /noise reduction/image sharpening/inverstelenc) do these settings only work with the supported accelerater decoders in this list -> http://www.nvidia.com/page/purevideo_support.html

Or may those features also be utilized on Decoders not in the list, such as mp4 (aka Divx/Xvid/3ivx)?

right now i assume not, but like i said, i dont know.
i do have a PCI-E 6800GS.

EDIT: another though: or am i mixing up those setting with the Decoder aplication that they make you pay for or have the 30day trial?.. and those vid options i mention above are for everything? not just the Decoders listed with PureVid?..... im apparently confused, if someone could clearify that would be great.

The controls work for XViD. I just tested it.

They also work for adjusting quality of video from my TV card.

PureVideo decoder is an MPEG2 (DVD)-only decoder as far as I know. So the settings in the decoder itself only apply to MPEG2 material. Someone please correct me if I am wrong.

PureVideo technology is different from PureVideo decoder. It is easy for people to get confused.

Actually I think they deliberately set out to confuse the two so they could sell you their own decoder, which most people find to be most excellent.

I bought the PureVideo decoder and like it. DVD movies can be played with Windows Media Player 10 with it and looks very nice.

Been using the Purevideo decoder and it's very nice. WMV hardware decode works incredibly well. The Step into Liquid video gets around 25% or less CPU usage. It used to hover in the 60%-50%(dual core). I can tell it works because when I use Power DVD to play the same video, CPU usage goes up, but when I use Medial Player, it drops dramatically.

That's because media player supports WMV HD DXVA( DirectX Video Acceleration ). 'tis got nothing to do with the PureVideo decoder, which is just an MPEG-2/DVD decoder.

Ah. So it must be using the purevideo technology on my video card? Hardware decode I guess.

Check out this article. As of their September 5th update, nVIDIA reigns supreme on video quality. This is also in comparison to twelve highend standalone DVD players one even over $2000.00.

My "Audio" and "Karaoke" tabs are suddenly missing. Any idea why this happened and how to get them back?
