Well THAT'S weird.

My googling also found the .ICEauthority tip so I tried it last night to no
avail (I was hopeful as there was ICE stuff in the gdb stack).  But before
I replied that it didn't work I wanted to give it another try to be sure
and now it's working just fine.

So I seem to be good-to-go right now.  For posterity here's the complete
list of my symptoms:

1) mythfrontend took a long time to start, even without 100% CPU.  Don't
know exactly what it was doing.
2) Once mythfrontend started, a randomish (maybe 5 to 10 seconds) time
later it went to 100% CPU when in the menus (main menu, watch recordings,
etc).  Everything was VERY sluggish but ultimately (and slowly) responded
to input.
3) During playback (with VDPAU) the CPU went down to a very nice 2%
4) I don't know if CPU went back to 100% after exiting playback (never
tried it, and now things work again).

Anyways, removing .ICEauthority seems to have worked.  Maybe last night I
did something stupid like removed it on my backend instead of the frontend
(separate boxes).

Thanks everybody,
