Help with iTunes and My Book Live

I have recently aquired a My Book Live as I am running out of space on my Mac, and thought that this would suit my needs with housing all my iTunes purchases, as this is the bulk of the data that is housewd on the HDD.

I have set-up the device as per the instructions with Twonky & iTunes server enabled, and the shared folder enabled to share all media types. But I am having issues with it showing the m4v files within iTunes, it is showing all my music files without an issue, so I’m at a loss as to why it won’t show up as I have done the exact same thing with the video files as the music files.

Is anyone able to shed any light as to where i’m going wrong?

Because iTunes server hasn’t worked for videos since iTunes version 10.2 and older.
