You may not have read it yet, but Anand wrote an update in his 6200 preview: http://www.anandtech.com/video/showdoc.aspx?i=2238&p=2
I'm going to start bugging BFG about this, even though they wisely didn't put anything on the box about the Video Processor. There's no point in bugging NVIDIA directly because they sell chips, not cards, and don't respond to card end-users. If NVIDIA doesn't have a fix "in a month" they should eat the cost of the recall/replacement since the NV40 is clearly a defective chip. The NV41 is coming out soon.
I personally emailed NVIDIA every other week from May until August asking for an update, with no official or unofficial response as to why nothing had happened with the illustrious Video Processor. Finally, when 23 out of the 35 slides of the NVIDIA press presentation about the GeForce 6200 featured the GPU's "Video Processor", I had had enough. It was only then that NVIDIA came clean about the current state of the Video Processor.
The Video Processor (soon to receive a true marketing name) on the NV40 was somewhat broken, 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).
NVIDIA quietly fixed the problem in the 6600GT and since the 6200 is based on the 6600, the 6200 also features the "fixed" Video Processor with WMV9 decode acceleration support...
NVIDIA is currently aiming to have us a functional driver and codec that will enable the Video Processor and take advantage of its capabilities in the next month or so; given that the feature has already been on cards (in one form or another) for 6 months now, we're just going to have to wait and see.
