[mythtv-users] Can I safely delete items from the capturecard table?

[stan]

I've got a machine that I renamed. Somehow his caused it to
think that the 2 existing capture cards in it, actually belonged to
a remote machien. So now I find that I have 4 cards defined. 

Cards 1 & 2 don't exist. Can I dlete them from the capturecard table?
Or better yet renumber 3 & 4 to be 1 & 2?
