Same issue with same playback error on my xbox one s this evening. Just purchased my first UHD from the Microsoft store hoping it would be better than Vudu. The movie is Sicario Day of the Soldado and I am in the USA. My bandwidth is 200 Mbps which is more than ample. It must of froze 7 times. Terrible experience and definitely will not purchase anymore movies via the Microsoft store.
