I just added 3 movies into a set in MC and all seemed OK.
I went into XBMC, removed the movies, cleaned the DB, re-scanned for new content.
Then in XBMC I went into Library mode, selected Sets and then saw the Set name I had just created in MC, and clicking on the set showed the three movies I had stored in the set. So all was looking good.
Then, out of curiosity, I dropped out of Sets and went into Titles in XBMC and I could not find the 3 movies in the set listed there. Is that the expected behaviour?
If so, that's a pity as I would like the movies to remain selectable by browsing by title etc, but also visible within the Sets view too.
Also, how can I control the order that the movies are shown within the set?
