Right.  In other words, the problem was caused by the steps you took 
before your original post ( 
http://www.gossamer-threads.com/lists/mythtv/users/162207#162207 ), i.e. 
you said:

So, had you not already deleted your channel config, Bruce's approach 
would have been an appropriate (and easy) fix.  But, once you deleted 
the channel config, you no longer had the source associated with your 
input.  So, I explained the problem you were experiencing after the 
delete without going into any details on what caused the problem in the 
first place.

However, the steps you used to fix the problem created by deleting your 
channel config were correct (or at least correct enough--they took you 
back to a known config (everything cleared) and let you configure 
correctly).  And, in this process--when deleting video sources and 
changing inputs--you do want to shut down mythbackend.  If you're 
actually changing video sources, your approach would work, too (assuming 
you also run mythfilldatabase).  However, as Bruce has said, those steps 
should not be used for miscellaneous changes to channel numbers in your 
lineup.
