> What is xvmc?

Xvideo Motion Compensation.  In lamen terms it offloads the video to
the graphics processing unit (GPU) from the CPU.  It's drawback is
that it generally only does mpeg2 decoding.

Not always no.  I think a lot of people on here suggest the Trunk
because it's been a fair amount of time since the last stable release
(which is a better guideline as to whether or not to use SVN/CVS or
the official release).  However, it's not absolutely necessary, it's
just that there are some really good code updates/upgrades/additions
in the SVN release that may make your system play nicer than the
latest release (currently 0.18.x).

Sounds nice, also sounds like a TON of overkill in areas that don't
need it if this is JUST a backend. :)

Certainly sounds like a decent enough system, as long you look into
and use XvMC, you should be able to playback mpeg2 content without

Good Luck!
