So I have purchased new batteries for my remotes, re-synced my movies, and all of my content is there to the best of my knowledge... THe issue I am experiencing is though I can see the start up page, I just cannot navigate throughout any of it. Is there a hard shut off or something else I can do from my computer, since I do not have access within my 1st Generation Apple TV?
Your Apple TV may have become paired with another remote. Hold the remote close to and pointed at the Apple TV, hold down the menu and Rewind buttons together for 6 seconds or until you see a broken chain icon on screen.
