The last NV40/NV45 Video Processor thread.
The NV40/NV45 contains a "Video Processor" dedicated silicon for hardware accelerated encoding/decoding of videod/movies and so forth...
"They promised full hardware accelerated MPEG1/2 and WMV9 encoding and decoding at 1080i resolutions." ...
"although it featured MPEG 2 decode acceleration. Apparently, support for WMV9 decode acceleration was not up to par with what NVIDIA had hoped for. As of the publication of this article, NVIDIA still has not answered our questions of whether or not there is any hardware encoding acceleration as was originally promised with NV40. So, the feature set of the Video Processor on NV40 (the GeForce 6800) was incomplete, only in its support for WMV9 acceleration (arguably the most important feature of it). "
(taken from anandtech: http://www.anandtech.com/video/showdoc.aspx?i=2238&p=2)
so there you have it... i believe PureVideo (the marketing name of the NV40 Video Processor) on the NV40/NV45 cannot decode WMV9 in hardware... but the 6600/6200s have their Video Processor fixed...

Re: The last NV40/NV45 Video Processor thread.
Is it true that PureVideo doesn't work with PAL material but only USA's NTSC :/ I've got GeForce 6600GT card and while tring to play my DVD with NVIDIA DVD Decoder screen is black and I can hear only the voice.
