Hi,
I'm not totally sure what type of remote control you desire here.
I use an all-in-one style remote from Logitech. It allows you to set up activities in the remote for seemless control of devices during that activity. For example, on of the activities on my Logitech Harmony is 'watch apple tv' i press the button corresponding to this, and my tv switches on, switches to the correct input, my bose system switches on and goes to the correct input and the atv switches on. All from one button press. Then of course you can do all your usual navigating through apple tv using the same remote.
Not sure if this is what you were looking for, but if so, i hope it helps lol
