When you configure a capture device with a single input, MythTV will 
always set the default input properly.  However, since kernel drivers 
have changed over time--in some (many) case(s) changing the input 
identifiers--this tends to happen when you add cards at different times 
(though it can happen when adding all cards at the same time if you 
misconfigure the cards--even if you think you undid the misconfiguration 
and reconfigured correctly).

The best way to fix the problem is to use the "Delete all capture cards" 
(not "Delete all capture cards on <hostname>") portion of 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 .  
Doing so will have no impact on your Channels or Video Sources (just 
don't do the "Delete all video sources" portion), and takes only 
seconds.  (I can delete all my capture cards and reconfigure the six of 
them--spread across 2 backend systems--in about 30 seconds.)

This is also why it's recommended that any time you do a major system 
upgrade (i.e. distro upgrade or kernel upgrade) you should repeat the 
"Delete all capture cards" procedure.

You'll also need to do as Stephen suggested to ensure consistent device 
numbering
