[mythtv] Firewire Problems (DCT6200)

[Bryan Murphy]

I've been having some problems with my firewire lately.   Last night I 
upgraded to the latest Ubuntu, and since then firewire isn't working at 
all.  I can pull a stream using test-mpeg2 from the libiec61883 library, 
but I can't get MythTV to do anything.   Previously, the firewire worked 
most of the time, and would only cut out after a couple weeks of usage 
(which a reboot fixed). 

There are two things I see happening:

#1:

I'm not sure what to do next.  Can anybody offer suggestions to help me 
diagnose the problem?

I've got Ubuntu Breezy installed, I'm running a custom install of MythTV 
CVS (as of this evening) running against a custom install of libraw1394 
(v1.2.0), libavc1394 (v0.5.1), and libiec61883 (v1.0.0) with a Motorola 
DCT6200 tuner.  plugreport reports the following:
