Is it possible to have two Xbox 360 consoles connected to the Windows Media Center?
Yes. When you connect an Xbox360 console to a Windows Media Center-based PC, a unique user account for the console is created on the PC. This account contains settings that are specific to the Xbox360 console. The settings include such information as locations on the Windows Media Center-based PC containing the music you want to listen to on the Xbox 360. The settings are unique to the console. Since the settings are unique, you can connect additional consoles to the PC. Depending on your Windows Media Center-based PC, you can connect up to five Xbox 360 consoles.
