The best way is to use mythtv-setup's "Delete all" button in the "Video 
Sources" section to delete all your video sources.  Then, re-create your 
video sources (and channels), re-associate them to inputs on your cards, 
and re-run mythfilldatabase.  Doing so will fix your broken channels at 
the same time as fixing the broken listings (which is why this is the 
best approach for you to use)...
