Bump up by how much?  I doubt I would make the jump, but I'm just curious.

What kinds of XvMC issues?  Also, is XvMC required?  I would not think so.
Ideally I would like a system that will play HD without XvMC.  If I can get
XvMC working well enough, then all the better (more CPU for transcoding and
commercial flagging while I watch).

We used to use the Asus A8N-VM CSM boards which are similar to the FoxCon..

That could be an issue.  Good point.

Excellent.  This is an important point.  Thanks.
