Hi, I installed the update yesterday, and have been generally happy with it. However, I noticed than when I tried to download podcasts, it would start to download, but then it would reset to the screen with the apple logo and then go back to the main menu. I thought that maybe restarting my Apple TV might solve this, so I mashed buttons on the remote. That didn't work, so looked online and then pressed Menu with the minus button. This also didn't work, and so I removed power and started it up again. It boots up fine, but it no longer responds to the remote. When I press buttons on the remote, the light on the unit changes from white to yellow. What does this mean? I've tried to force repairing of the remote using menu and next, but this makes no difference. I can't do anything with my apple tv now- please help!!
