I don't think it's an issue with DG2, I just booted it up and played a couple levels without any issues but I'm having a strange issue since the update that's similar to yours that appears to be controller related.
I've had both Hulu and Netflix shutdown and take me back to the dashboard. I've also had the window pop up several times asking if I wanted to shut down the console or controller.
My Kinect isn't hooked up and I use the controller to navigate apps/dashboard. All the above happened shortly after I had turned the controller on to navigate Hulu/Netflix or the dashboard and the controller blinked just prior to the above happening.
It's like the home button on the controller has a mind of it's own ( has happened on two different controllers). It doesn't happen every time I turn on the controller so I can't reproduce it.,,,,very strange.
BF 4 Fifa 15 now when I go to play them games the console will go blank and go back to the dashboard I have to start them up 2 r 3 times before they play. They are downloads from the store Idon't have the CD. Thank
