iTune's movie keeps stopping

Hi there,

I find that when I am watching a movie I have purchase on iTunes, randomly the screen will go black and the movie will stop playing. The only fix I have found for this is to cancel playback and go back to my library and hit play on the movie (or tv show) again.

This becomes infuriating as it happens every few minutes. I have tried updating the iTunes app on my laptop and it doesn't seem to help.

Does anyone have any feedback on this issue! I have movies I have bought and haven't watched yet because I know this is going to happen :(

Thanks!
