Okay. But this dialog must not stay forever on the screen waiting for user input. I use a single remote control (HDMI-CEC) to startup/shutdown my TV, AVR and XBMC box, all with a single click on the TV remote. If I shut down my system using the TV remote, the screen switches off first, then the AVR, last the XBMC box. And in this scenario, I simply cannot see the YesNo dialog... Thus, a YesNo dialog would be fine, but with "auto dismiss" after a certain amount of user inactivity.
