Is there any way to connect Remote App to apple TV without iTune?
iTunes does not need to be running to control AppleTV using Remote app.
It simply allows you to access those itunes libraries directly or via AppleTV when they are running.
yes, but to connect pair remote app with Apple TV, you need iTune?
Not as far as I can remember.
Which AppleTV - 1,2 or 3?
With AppleTV2/3 Remote app works via Home Sharing credentials entered on the iOS device.
With AppleTV1 you have to enter a code but that is not in iTunes.
