hmm... I may have been unclear. The .img is just the Raspbian OS (no XBMC), once you install the Raspbian OS and expand the rootfs to use the whole card (you'll see that option on first boot), you can either build XBMC yourself or download an installer package. The installer package is significantly quicker, but will ultimately include the features someone else decided are worth including. Building it yourself is much more complicated and takes a lot more time, but gives you the option to include as much or as little as you decide.
Release version. The guys at Xbian are giving me some 'experimental' pointers.
Xbian after install if I do nothing and shutdown then reboot seems fine - starts every time.
But once I add music, wifi etc. just wont reboot
