Firefly won't recognize video?

Just set uo Drobo FS with Firefly. Copied music to Media folder and iTunes plays those files perfectly. However, my mpeg4 videos I’ve ripped with handbrake aren’t recognized. I can’t see them in the Shared folder in iTunes, yet the very same videos play perfectly in iTunes library on my local hard drive. Did I miss a step by just pasting these files into the Media folder, same ass the music files?

To be clear, the video files are mpeg4 with an extension of .m4v
