There is one device that is Media Center specific, and other third party devices that have been known to work using different tools.
Medio will use the same controller. And there are Grid products that will take third party controllers and convert them to be used with Medio.
My advice, find yourself a good RF Mouse Pointing device and a Jukebox software that supports Mouse Interaction, which is pretty much all of them.
Otherwise, I'd probably be looking at something like a streaming media device like the Audiotron or the Omnifi from Fosgate.
