Movies Will Not Load on Apple TV

HI,

For some reason movies to rent/buy and watch now/later have recently decided to not load on the Apple TV. After about 3minutes of watching the circa trying to load, the system automatically restarts and I am back to square one.

I have reset the system, and in addition my router but no joy.

The trailer for each movie works fine, but it will just not load the films???

Any help on the matter would be most appreciated.

REgards,

Jez
