Switch off Apple TV 1 Gen (XBMC Gotham OS)

When I choose in the XBMC menu to switch off my Apple TV, the system is switched off, but the white light in front of the Apple TV remaines on. Every time I need to pull the plug !!??!!!
Thanks for the help.

Everything seems to be working fine, except actually turning off the AppleTV. The White LED stays on.
We have a period of extreme heat right now in Switzerland. Really turning off the AppleTV would help heatwise… :wink:
