Seems somebody imported a 0.18.1 database into an /already existing/
0.20 database (i.e. created a new 0.20 database and then imported
data).  Therefore, Myth did /not/ upgrade the database data to its new

So, right now you have a mess of old and new format data.  The best bet
is to start with your 0.18.1 DB (backup and then drop the current DB and
import the 0.18.1 DB), let Myth upgrade it (by running mythtv-setup),
then bring in the new recordings, if they're worth the trouble (I'd
recommend using myth.rebuilddatabase.pl).  If you only have a few
off-season recordings since the upgrade, I'd just re-record them.
