[mythtv] Ticket #11752: Recordings may end up in live tv group

Sorry, I did kinda go on a rant... but not at your proposal, just at
your claim of the "only case where it makes sense is a less-than-ideal
system/storage configuration..."

And by the way, there is no reason you can't place your livetv SG in a
directory next to your recordings storage group.  Mythtv recognizes
that they are on the same media and balances them as you would want...
so it's every bit as efficient as not using it.  But I agree that it's
silly to put it on a separate partition... livetv is always expired
before recordings anyway (at least on my system).
