Yeah, it sounds like yours are in alternating order, which prevent 
MythTV proper properly utilizing multirec (and will break both 
recordings and Live TV).

On the bright side, Delete all capture cards and then re-creating 
capture cards and re-connecting inputs takes all of 2 minutes, even at a 
slow pace.  With my 6 cards on 2 backend hosts and differing capture 
card (Live TV) and input (recording) orders, it takes me 30sec to delete 
and re-configure.  It actually takes me more time to shut down the 
system so I can run mythtv-setup than it takes to reconfigure it.

Oh, and with Delete all capture cards, your channels are not affected, 
so you won't have to rescan or anything.
