Rented Movie displaced photos

Greetings,

I rented two movies over the last two days and when the movies were downloaded they took up quite a bit of space on my atv hard drive. I then was trying to show some photos that I had synced to the atv and found that the photos were now gone. Try as I might, I could not get them back - until I deleted one of the rented movies and re-synced all the photos. This took some time as I have about 850 of my over 12000 photos synced to the atv.

Is this a feature or a bug? Shouldn't this automatically restore previously synced data?

Thanks
