I'm facing a similar crash which is coming only from 8.4 devices.

There's a workaround to send -stop to the videoplayer before chaging its contentURL, but it doesn't seem to help in my case.

you cannot have same item associated with two different players. Recreate the item or null the player with which it was associated with.

According to my crash logs reports, this issue seems to have vanished in iOS 9 without changing how I use MPMoviePlayerViewController.
