Yes that might be. In the meantime I just set up everything from scratch using the other tutorial from you.

It took me some time to set up everything the way it needed to be to boot up (/dev/sda or sda1 or sda2...).
Finnally I found out that the MiniPartitionTool did not a clean job in formatting my SD card and USB Stick.
The 16GB USB3 SanDisk Stick allways had a free non partitioned space at the end, even if I told the tool
to use the whole space to set up a FAT32 partition. Once partitioned and formatted with the windows own
drivemanager it worked flawless and booted up and installed everything the way it should.
The thing crashed on me a few times setting up everything in OpenElec. I lost the complete configuration
after these crashes, the Raspberry Pi booted up and restarted the complete setup again no idea why.
Now, the fourth set up worked. I could change language, set network IP, mount my NAS folders for
music / movie and photo and even scraped all my movies. Today I entered the MPG2 and WVC1 licenses
and the device is still running.
I experienced that if you try to shut down the RPi it will reboot which seems to be a known problem. I
think that was the reason why my configuration got lost several times yesterday. If you just unplug
power to the RPi because there seems to be no way to safely shut down the device it almost everytime
crashes the configuration. Right now I will not try to shutdown or reboot the Pi, I'm afraid I again can
start from scratch if i disconnect power to it.....
