Hmmm...Well I built the lastest SVN and I'm using nVidia 9631 drivers (not
quite what you have) and I've still got lots of problems.  Of course, that
might just be my CPU.  I can playback using XvMC with just a bit of
hiccuping.  For some content, I can keep my CPU down to about 70% (on my P4
2.4GHz) but for much of the programming it jumps to 99%.  The heavy X
utilization has disappeared (both with and without XvMC).  I'm not sure why

In short, I'm still lacking a viable HD solution (even with XvMC running).
