Alright, I was testing very quickly. I'm now correctly using 

xml:
<onclick>RunScript(script.metadata.editor,action=setuserrating)</onclick>

, were it works! movie.nfo <userrating> is correctly updated.

However, when Emby refreshes the entry with the new .nfo, the rating disappears from Kodi. The movie.nfo correctly states 

xml:
<userrating>3</userrating>

, but Kodi displays "No rating". I don't understand why this happens. I know you work with Emby, so I was hoping you could help me.
