My girlfriend was watching a DVD on my Xbox while I was at work. She told me that the controller came on by itself and then the DVD froze and flickered off. Then a loading screen came up and starting displaying a video that I can only call pornographic on the Xbox video app. I have never used this app nor knew it existed. Now when I go on it and look on recent videos it says I have never used the app. Any help will be greatly appreciated thanks.
