Hello,
I just purchased an apple tv 2nd gen off of ebay with no remote, is there anyway to access it with my iphone, I have installed the app remote but cannot get access. thanks
If your on the same network the remote app should work. The apple tv can also learn pretty much any remote but you need a remote to make your way to that part of the settings.
I'm thinking you will need a physical remote to turn it on and navigate to the Home Sharing option to log in so that you can get the Remote.app on the iPhone to "see" it and use it.
