Mali 400 is used by the Amlogic 8726M chipset which is what powers Geniatech ATV1000/2000/3000/4000 players. It does not support ISO playback and it is not a good media player for a movie collection, the media player is incredibly basic even more crude than your AC Ryan player and the remote is not great either. If XBMC ever gets ported to Android 4 one day (not any time soon) and assuming Geniatech release a proper version of Android 4 then it could be a great player (stock remote still sucks though). No idea if bluetooth devices work. I think you'd be better off with something like the Boxee Box instead.
