Help! can't play movies after turning on Restrictions on iOS 8.1.1

Hi guys please help me solve this issue..

I have synced a couple of movies from iTunes, then turning on restriction on Movies in my iphone 6+ (iOS 8.1.1).

After checking that my movies really "dissapear" from Videos app, i turned off the restriction again to access the movie. There has been no problem after I turned on the restriction again and wait for a couple days.

A couple days later, I want to access the movies again, so I turned off the restriction. But when i open the movie it doesn't play at all, and just return to the video summary screen, as if the movie had ended. And on top right corner there is a thin circle line like it was trying to download something, but it never really progressing to any stage.

I have tried restarting the device, turning the restriction on and off, to no avail. Finally I erased all movies and synced it right back using iTunes and the problem dissapear, but I did the same thing and a couple days later it happened again.

Please tell me that there are other ways to solve this other than re-sync to iTunes or via iCloud. Cheers!
