Right. And, this is the way to go (even if NVIDIA releases some Linux
"PureVideo" API) because it's standards-based.

Also, lower-end GPU's are not likely to support complex-enough shader
programs (basically, you'd probably need something like a GF6800 or
better, though I wouldn't be surprised if the 6800 is even too
limited--after all, it took NVIDIA until after they released the 7800 to
demonstrate that it could be done on a 6800, so they may have taken some
"shortcuts" when decoding with that GPU).
