This is really odd. On my iPad I see all my movies, bus some show their proper folder artwork, but others get what looks like a screen grab from the movie. I have tried turning off fetch meta data in the settings, if I do this all the folder artwork vanishes. If I turn it on the same show their folder artwork, some don’t. However, all of the moves are properly found and show all the correct metadata information when opened.
Just to make things even more confusing, on my appleTV all the folder artwork shows up properly, it’s just on the iPad that they don’t. For example, on my iPad the movie 28 Days does not show the proper artwork, just a screen grab, but on my AppleTV, the same movie shows its proper artwork.
I’ve enclosed a screen shot to explain
