Hey Man,
We don't have Xbox1 support yet...
We may build something for it in the future, as our ultimate goal is to be available on all platforms that can play video (XBOX1 being a platform of that sort), but we can't say when that will be... So if Popcorn Time is a must for you (we're thrilled to hear!!!), then go for a PC for now, and add a Chromecast device to cast movies and TV shows to your TV screen (we just released the alpha with chromecast support and soon the beta will be out).
