Help adding a movie;

Hi there. I recently ripped my copy of the Lord of the rings blueray extended trilogy. My folder structure is - Lord of the Rings Trilogy BluRay Extended [2001 - 2003] than each movie is in its own Folder within that, The Lord of the Rings The Return of the King [2003] -> The Lord of the Rings The Return of the King.mp4 etc.

My problem is, the first two movies added fine/scraped to MC (using MC 3.429b Weekly), at which point I was able to add them to a SET and could see that set within XBMC. However, the third and final movie USING THE EXACT SAME FOLDER AND FILE STRUCTURE is not showing up in MC at all. It appears to scrape, but is never added. It downloads fan art and the .tbn and the folder image but does not create a .nfo file.

SO now in XBMC i see the set, containing the 2 that added to MC fine, and below that (out of the set) the third and final movie. Its infuriating me.

How can i fix this, or bypass it so it shows in the set within XBMC? do i need to manually create a .nfo file :S

plz help
