Video drops out on Samsung TV

With my Apple TV 4th Gen and a new Samsung UN55MU8000 TV, some content plays fine and other content has no video.

Examples: Spectre, streamed from the iTunes store, will play perfectly. Kingsmen The Golden Cirlce will show a couple of seconds of video and then go black. I can still hear the audio, just no video.

What settings do I need to change to get this to work?

Thanks
