I'd give up. The device is nice, but Apple TV programming is an absolute joke! If you try to duplicate a library the "program" changes all the file types from whatever you entered them as, to "Home Video." It would be so easy to fix, but Apple doesn't care. The program also randomly loses information stored in the "Description" field, This one cost me dozens of hours. My solution was to switch to "Subler" for the metadata situation. It's been working nicely for me for weeks. I also switched to "QuickTime Player" to play the files, because QTP has Air Play capability which many non Apple programs do not.
