Just for the sake of completeness, I figured I would post the solution 
to this part of the problem I was having with mythbackend.

Because I removed and re-added the capture cards within Mythtv-setup 
(something I didn't need to do since the problem turned out to be 
related to the serial port on the computer), the default input 
connection was reset to "Tuner 1".  I have three set top boxes connected 
to my backend, all of which are connected via the s-video interface.  
Although I had the right settings in the "input connections window", the 
cards (under "Capture Cards") were individually set to default to "Tuner 
1", which, on startup, caused the error (not a critical error, but an 
error none-the-less) as shown above.

I fixed it by setting the default input to "S-Video 1". :)
