Guess I should have also mentioned that it's designed this way to allow 
for flexibility when a) you don't boot one or more remote backends (and, 
therefore, don't have access to their storage/recordings) or b) you have 
unmounted file systems or c) you lose files after a HDD failure or 
whatever or d) other things that cause you to lose recordings.

So, we are very much interested in making sure MythTV never has a 
problem when your files are out of sync with your metadata, so this 
won't change in the future, either.
