The invocation of ttvdb.py seems to come from https://code.mythtv.org/trac/browser/mythtv/mythtv/programs/mythfilldatabase/xmltvparser.cpp#L530.

I'm not sure this was taken into account in b64be0f8, but calling the script(s) for potentially every program seems a bit unnecessary.  Unclear if this is the cause for long runtime though.
