Shut down your backend and run mythtv-setup again. You can delete and 
re-install cards without affecting your program lineups (although you 
will have to re-designate the card-lineup combinations).

At the top of the screen when you create a card entry, you can give the 
card a name. That name (hopefully a distinctive one) shows on screen 
OSD-style when you go into Live TV etc or change tuners.

You should enter your cards in reverse order to your expected recording 
use, since myth selects cards starting with the last and working forward 
  for recording, and leaving the first one for liveTV use.

To be absolutely clear, you could shutdown the machine and remove the 
Divico tuner, so that the tuner found by mythtv-setup *must* the 
Avermedia and it will be forced to be dvr0. Thereafter the only way to 
tell which tuner is being used in the Divico will be by way of the 
distinct name and ordering you use in mythtv-setup. It does not really 
matter which physical tuner on the card is #1 or #2, but you will know 
which named unit is being used.
