[MPlayer-users] XvMC question

My understanding from reading this thread:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&threadm=1021820061.3281.75732.camel%40tibook&rnum=1

was that XvMC provided asynchronous double-buffering facilities that would
benefit any codec by allowing the CPU to start processing the next frame
before the DMA for the previous frame was complete. Is this incorrect?

Not that it does me much good. I spent an hour investigating XvMC and
recompiling MPlayer before finding the following line in NVidia's README:

This release includes support for the X-Video Motion Compensation (XvMC)
version 1.0 API on GeForce4 and GeForce FX products only.

I have a GeForce2 MX. D'oh!
