Thank you for your response.
How can I persuade Sonarr to use these particular aliases? They don’t appear on TVDB anyway. That’s the problem. I can guarantee that they are used for WWE episodes to be found weekly on various torrent sites - Monday Night Raw and Friday Night Smackdown. The same aliases are confirmed on IMDB. The frustrating thing is that Sonarr accepts WWE Raw and WWE Smackdown, (the same show) but there are no torrents for those. When I manually add the downloaded shows to Sonarr they are recognised and accepted but as WWE Raw and WWE Smackdown shows.
I have created an IMDB watchlist for both series, but unfortunately I get an error when I try to add it to import lists. (ls541916805) I have created a thread for that particular issue, but have had no replies.
