My personal opinion would be to split your systems.  I'm a believer of
dedicated systems for dedicated tasks (to a certain extent).  You'll
find much more flexibility with splitting the two systems up imo.

You *might* be able to play back hd with you 3000+ (which is not the
same as a p4 running at 3GHz btw) if you split your systems.  I would
give mythfrontend a higher priority and see if that helps as well, but
making your 3000+ a dedicated frontend might free up enough resources
to let you get rid of xvmc.  But it is on the low end of being able to
playback HD.

And HD over wireless?  Brave man.  Good luck with that.  802.11a will
be your best bet.
