I'm running iTunes 11.1 and occasionally a movie will not add to the library. My library is stored on an external hard drive and, after trying to add the movie, the capacity of the drive will decrease so it's going somewhere. It will not, as I said, show up in the library, and it is not in the iTunes media folder when I navigate to it in finder. I don't want to keep trying to add a movie that I then can't find anywhere but is taking up drive space. Any ideas? I'm downloading the iTunes update as we speak so that will hopefully resolve the issue but I'd still like to now where on earth these movies are going!
