How does WD recognize TV Show? Firmware Version 3.00.28

Im using USB 2tb storage for TV and a seperate 2tb storage for movies (both exactly the same).  The odd thing is as I have mentioned, I have no issue with geting the info for movies; backdrops display correctly as well as the info  etc, however for some reason for TV eps, I cant get the backdrops to display.

As a further note; I did attempt to do the same thing with TV eps onto the internal storage on the Hub, but again to no avail. Episode name etc all displayed correctly but alas no backdrops :cry:

Suggestions…??
