I believe this to be a security feature on Roku to help stop the copying of movies and content. It also happened to me trying to use Roku through another device.
You have to buy a 24.99 roku express

Have you tried using another HDMI port on your Roku TV as well as switching out the HDMI cable used to connect your XBOX1?
