thank you for the information.
what do you think, can I load an image for the Pi to another device, for example the open-elec-box / openhour / orbsmart / beelink? normally, it should work, all the devices are RISC based androidboxes...

The Pi doesn't run Android so this won't work.

and another question, is the XBMC nightly (or any other KODI release) build able to play 3d.iso files?

Milhouse nightly builds do have early support for 3d ISO files.
