How to switch from HDMI to composite on XBMC exit

[udrnovsek]

Thanks for your hints.
I tried some options without loop but at last this one i posted worked for me.
I'm not familiar with bash scripting (yet).
The loop is there cause i don't want to exit into system console. I just want that XBMC is restarted again every time i select EXIT from the xbmc menu. After exit XBMC it restarts and appears on composite output and after next exit restarts automatically and appear on hdmi output.
I use only mouse (no keyboard) on the Raspi (in my ht room) so i cannot type into console 'xbmc start' or 'xbmc stop'.
It would helped me much (and others) if i could find in documentation some description about how the startup process of the xbian/xbmc goes (what scripts are invoked in what sequence) and the of course the stop sequence.

Anyway guys, you are doing a great job.
Hat off.
