Well, that's just it...  there's really nothing 'noticeable' to fix 
up...  The mythfrontend still seems to be fine...  It was only because I 
was experimenting with my DVICO remote control and looking at dmesg that 
I noticed all the 'errata' from this 'apparent' problem.   I was hoping 
someone in development might recognize what's happening and elaborate.  
If nobody comes up with anything, I'll play around and see if I can 
pinpoint what is causing all these 'warning/error' messages.
