Stop RPi from triggering HDMI on TV while booting

[IriDium]

As @rikardo1979 said - this is not the perfect set-up.

By powering the RPi via the TV port, shutting down the TV will KILL power to the RPi - and as Xbian is a journalled OS, corruption is inevitable which will make the system unusable.

Far better off using a separate PSU for the RPi or ensure that Xbian is shutdown correctly before powering off the TV. (For you will, even with the best of intentions turn off the TV before Xbian is shutdown). Thus, I and few other people will not support you if you do have problems after that.

However, it is your RPi, do whatever you want.

I believe that if you have a play with the settings in SYSTEM -> SYSTEM -> INPUT DEVICES -> CEC ADAPTER -> "Make XBMC the active source when starting" should stop the problem you are describing.
