Xbox Blu Ray App Not Working

Hi

I currently have an issue where I' am unable to play DVD's. I downloaded the Blu Ray app and when it goes to play the movie I get the blu ray screen. The little circle is there like it's loading but I can hear the movie playing. Yesterday I spent an hour
and a half on the phone with the tech support. We did everything. Even talked to the Network department to see if it was our internet. We changed all kinds of stuff with our internet. When we tried again, same issue. The line for some reason disconnected.
I don't know what to do. I don't understand why it won't work

:)

I dont think they can fix it and they have even started locking threads on the subject.

The X1 is amazing for gaming but it struggles with anything else imo!
