Hi all. I got an AppleTV for Christmas and finally hooked it up around the end of February...and I've used it cumulatively around 3 hours total. However, the past couple days, I've had it on playing music on shuffle and it plays for a good two to three minutes before rebooting itself... I've tried unplugging it, tried factory restore, tried updating the software, thought it was my Airport Express at first, but I updated that firmware as well, and everything on my network is perfect. Does anyone have a clue as to why I'm having this issue? I've researched a little and all the answers I can find so far are take it back to the Apple store and have them exchange it. Will they exchange it this far into my having it? Especially without a receipt?
