The Media Center Remote for Windows 8 UI app along with the corresponding Media Center Remote Command Listener can control your Windows Media Center computer over the Wi-Fi in your house. You can browse your music, picture, and video libraries on your Windows 8 device. Search for songs, artists, and albums to play or queue or browse your collections as well as playlists to play on your Windows Media Center computer. You can also play pictures and picture albums, or videos.
The app also provides the ability to control basic functions like play, stop, previous, and next, along with volume and channel control. You can control the interface from your Windows 8 device using directional buttons or a gesture pad to 'swipe' through the menus. There is also remote keyboard functionality.
Please note that this application currently does not support Recorded TV yet.
There is also the ability to snap the app to have a Remote Control while running another app like a browser.
Extenders such as the Xbox 360 are also supported.
My Media Center add-in called the Remote Command Listener is required for the remote to connect. It can be found at: http://www.themediacenterproject.com/RemoteCommandListener/
