I use this for Plex, because their guide for the UK has loads of data errors and weirdness.
Quick and dirty container for Schedules Direct to XMLTV.
To configure, use /opt/app/tv_grab_az_sdjson_sqlite/tv_grab_az_sdjson_sqlite --manage-lineups and then /opt/app/tv_grab_az_sdjson_sqlite/tv_grab_az_sdjson_sqlite --configure
For a manual run use /opt/app/tv_grab_az_sdjson_sqlite/tv_grab_az_sdjson_sqlite --output /output/sd.xml - This command is automatically run every two hours
Mount /output to your output directory and /root/.xmltv to a config directory
