nVidia's gpu_videoeffects sample

Hey, it’s just the usual: “it doesn’t work with latest whql drivers”. I’m trying to get video texturing to work in my app too, so I thought I’d give the source a look (even if it doesn’t work)…
Well, I’m a bit confused. There are lots of places with code for VMR9 support, but most of them are commented out with “#if 0” how does it work then? Also, in VideoPusherPBO, there are dozens of very similar functions that are supposed to upload the data to a texture. Well, they all use memcpy to PBO?? What’s the point in doing that? If you have to use memcpy, then you’ve already lost all of the benefits, no?
Anyways, I’ve thought I’d post this here, maybe someone had more luck with it.
