They are from mythfilldatabase, but they are
notices, and not errors.

In the case of OTA, do you have translators in
your area?  For better or worse[0], there can
be (and often are for at least a subset of the
channels) different XMLTVIDs for each
translator.  So, depending on your specific
location, you might get channel 2.1 from
one tower, or channel 2.1 from the other
tower, and they have different XMLTVIDs,
so the Schedules Direct data provides both
schedules (and, if you dig deeper, each
translator has a different FCC callsign, and
typically different name).  However, even
though they have different XMLTVIDs, the
actual schedule is the same.

The easiest solution is just stop watching
for notices.


[0] I have previously asked that the upstream
use the same XMLTVID for all translators
(or none, rather than being miss or hit), but
the upstream was convinced that there was
no reason to change.  FWIW, they do the
same thing for (some) cable channels, where
the SD version and the HD version of the
channel may (or may not) have different
XMLTVIDs.
