The 'quick tune' you refer to is how the selection of digital streams is 
done.  Rather than waiting for the program table to tell it where a 
stream is, it simply filters on where it should be.  If all goes well, 
you're looking at a few fractions of a second faster tune than normal.  
This is unnecessary for scheduled recordings, and has nothing to do with 
your problem.

The scheduler matches channels based on number and callsign.  If those 
match, MythTV will assume they are the same thing, and will schedule as 
such.  That means it will use the first available tuner to record, which 
seems to use the source with 'channel A'.  If the channels are not 
actually the same, name them something different.  If one is higher 
quality, either re-order your capture cards so it is first, or mark the 
lesser quality channel as hidden.
