Mac OS Apple TV App has crazy video...

Hi Folks,

I've been watching Apple TV on my Macbook Pro ever since my iPad died a few months ago, all working perfectly until this week, when it now plays tv shows back as garbage - please see attached images. Trailers before the shows themselves play fine, but as soon as the show starts, it's a mess of weird colours.

I've checked shows I've previously watched on this same Macbook Pro and they now give the same video output. I don't know what's going on! Movies I have bought from the store play fine, even as a stream.

Seems like it's anything via Apple TV streaming, tv or movies. No idea why it's started or how to fix it!
