Theater Mode is broken & doesn't work (Proof)

When ever I try to capture need footage for my YouTube channel, the game just won’t let me play any clip no matter what I do.

Here’s a video of me showing that I can’t play anything in theater mode. I’ve rebooted my Xbox One numerous times. Currently installing the entire game over again. This is really annoying.

Laughable.
