[mythtv-users] Duplicate matching doesn't seem to work with blank subtitle

Absolutely.  If there's no subtitle, Myth has no way to differentiate
between specific episodes (I would argue it should also support
duplicate detection using other identifiers from the guide, but
unfortunately that's not available, at least in 0.20), and so it errs
on the side of caution and records them both.
