If you are not fully satisfied with your FrontRow, you can install AppleTV`s "FrontRow" using ATV4mac installer from macgeekblog. The on-line installer made by macgeekblog guys weights only 1.6 mb and will download and install all the files for you: around 60mb.
You can install ATV only running Tiger (10.4.8 and up) as AppleTV runs modified version of Tiger and due to that there are many incompatibilities with Leopard`s Frameworks. ATV4mac was updated today so go and grab it!
