No need to do that it will just be ignored when you have MYSQL configured.
Well not from your MyVideosXX.db but from your MYSQL database.
So to troubleshoot I suggest you first start on the Pi that has your MYSQL server running.
- Enable debug logging
- Browse a bit thru your library (e.g. play a movie shortly)
- Upload logs with
grab-logs -A
and share the URL
You also manually can check if the databases are correctly created. Log into OSMC with ssh and run mysql -h localhost -u osmc -p
when connected that run show databases;
