Here's a little more info on the "unable to contact Mythbackend" 
situation.  I cold booted the machine into Mythtv and tried "Watchtv". 
I immediately got the backend error.  I then escaped out to the desktop 
and opened a terminal window.  Myth backend was running so I thought I 
might learn more by stopping it and then running it in a terminal 
window.  Here's the way that went:

[root at mediacenter mythtv]# service mythbackend stop
Stopping mythbackend:                                      [  OK  ]
[root at mediacenter mythtv]# exit
[mythtv at mediacenter ~]$ mythbackend

Be sure that '/storage/recordings' exists and that both
the directory and that file are writeable by this user.
Segmentation fault
[mythtv at mediacenter ~]$

That raises some questions.  The lockfile is currently owned by root, 
while the directories are owned by user mythtv.
Who normally owns mythbackend, mythtv or root?  If mythtv, how could 
root get to own the lockfile?
What's going on with the segmentation fault?  And FWIW, I'm running an 
i686 P4 with hyperthreading.
