XvMC supports offload of MPEG2 Motion Compensation (which is the "MC" in XvMC) and iDCT (inverse Discrete Cosine Transform). iDCT is the more CPU intensive component of the two. But, I think the i810 only offloads the MC. So, you probably won't get much boost out of XvMC on that platform.
A Google search turn up this page, which talks about the capapilities of various cards with DxVA, the Windows equivalent to XvMC: http://www.elecard.com/technology/dxva.shtml (Note that it doesn't include the newer NVidia GeForce 4MX or GeForce FX cards, which support full iDCT offload in Linux.)

So from what i've read, XVMC was originally developed for the Intel 810 chipset, but I can't seem to find any information on how to get it working with anything but nVidia video cards.I'm running FC4 on a fairly underpowered (700Mhz) box. I actually have 2 of the same boxes, but one uses a PVR350 and therefore uses the accelerated output, but my other box uses VGA for display, and I get really choppy video without XVMC. If I enable XVMC in the setup screen, I get "Can't initialize Video" messages when trying to playback a recording.Any tips/tricks that anyone on here knows about?Thanks,Jeff
