The ones dated 2020 are from the last time I set this up.  It looks like,
per your post, the .xmltv files I generated over the weekend did not
overwrite the old ones, but were assigned to .TMP extensions.

Do I need all those DB files under ../.xmltv? What else do I need to do to
straighten this out, hopefully without wiping out existing recordings?
