Movies not being copied to external USB

I am connected via FTP to my appletv.local, and have put a few of my movies into the “Movies” folder (and they show up on AppleTv). I have selected to use the external USB drive as my primary iTunes storage. The problem is that the movies I transferred are not going to the external USB drive (see output below).

Before transfer…
-bash-2.05b$ df -h

After Transfer…

My first attempt was to add my movies from my local mac attached USB to iTunes (while holding down the option key), such that iTunes would have a reference to the movie but leave the content on my external drive. The problem here is that the .m4v would not sync to AppleTv. This would be my preferred solution.

Anyhow, neither seem to work. How can I get my movies on the external USB?
