The TV show is not scraped by Kodi and an error is written to Kodi saying there is no episode guide. When I then manually edit the NFO file change it to the moviedb episode guide the TV show is scraped correctly by Kodi.

That is correct. The <episodeguide> URL is provided by the information provider in a format that they have designed. The URL is not interchangeable between information providers. i.e. you cannot use the TVDB URL while using TheMovieDB scraper.

Another option is to just delete the <episodeguide> tags and everything between. This will only work if you have episode nfo files for all your episodes. It also means that you need to continue using nfo file for that show unless you Refresh the tv show (not the episodes) in Kodi which will download the new <episodeguide> URL.
