How do I completely reset my first generation ATV without a Mac (I currently do not have access to the Mac that it previously synched with)? I am using my Macbook Pro and it does not show up in iTunes on this one. Something is not right with the AppleTV and I am unable to see anything on my TV from it so I want to try wiping it. I have already tried unplgging and plugging it back in. I just realized that my home network name has changed since I last synched, guessing this might have something to do with it. Thanks!
