Got my new Pi 2 and installed Raspbian - works fine. Same Pi, same SD card with raspbmc: Not booting. When I plug in the power, I get a red and a green LED for a short time, but then the green one turns off. On the screen I just see that colorful square you see on every boot. I've already tried using the python script from http://www.raspbmc.com/wiki/user/os-x-linux-installation/ and dd'ing the raspbmc image from http://www.raspberrypi.org/downloads/ to my SD card. A also downloaded the OpenELEC image and it doesn't boot either.
Any hints?
