Yep.  That's definitely the best way.

The fix is to not "disable" the capture card from mythtv-setup but to 
/remove/ it.  You should not define any capture cards in Myth that do 
not exist.  Note that Myth does not support having defined but 
non-existent capture cards and does not support having defined (and 
existent) capture cards with no connected inputs (the latter case often 
seeming to work, but mysteriously just failing to work at some point in 
the future--sometimes months later).

You can delete a capture card by hitting 'D' when it's selected in 
mythtv-setup, but the "Delete all capture cards" approach is better.
