No idea.  And, really, no one runs with that configuration.  Until 
someone who feels it's a good idea to configure MythTV to define things 
it can't use figures out what breaks, I will continue to say it's not a 
well-tested configuration.

Capture Card order has no relevance to recording input selection order.  
Capture Card order only affects Live TV input selection order and /only/ 
if you enable, "Avoid conflicts between Live TV and scheduled shows."

Input Connection order specifies recording input selection order.

And, whether you delete the Capture Card (which deletes the Input 
Connection) or you delete only the Input Connection, you lose that Input 
Connection order.

/me thinks what you're trying to say is, "I still think it's a little 
weird that no one (including me) has taken the time to sit down and 
write a UI to allow users to move cards and inputs up or down in the 
recording/Live TV input selection order."

While you can't do anything about the rest, you could do something about 
the "including me" part.
