Obviously I can't see straight.  The CPU is using a LOT more processor then it
should.  I've been used to seeing only around 40% on the backend in the family
room.  Maybe the extra 200 mhz on the backed was enough for it to play back HD
that I didn't notice that there was a problem.  So I think something has changed
in SVN that is requiring a lot more cpu usage that what it was using.  I'll
upgrade to current SVN and see what happens.
