I have an M2 hooked up to the newest DirecTV box using an HDMI-to-component adaptor. Everything is hooked up properly and the TV signal comes through to my iPhone 4 just fine, but I cannot change the channel from the app. I can only watch the channel that the DirecTV box is set to. As my iPhone 4 is limited to iOS 7, I cannot upgrade any farther from SlingPlayer 1.0.0. Can anyone help me?
