I suspect this issue as the cause:
https://code.mythtv.org/trac/ticket/13518. I see the problem mentioned
in this issue in my logs, and I think the failure to fetch thumbnails
may be shortcircuiting some of the code used in selecting best match.
As a cause of the issue, I'm suspicious of:
https://github.com/MythTV/mythtv/commit/49e987798ace7d125496cbf874b6bcf43791c8fa.
In theory, such a change shouldn't cause change in behaviour, but is
const foolproof?
I'll see if I can track it down further when I get a chance.
