I have been doing lots of XBMC testing with Raspbmc for the Raspberry Pi but there is also another version of XBMC you can use. OpenELEC is an imaged based download for the Pi and there is a new build of it out today. The image is based on OpenELEC from September 2nd and you can download a 1GB SD card image or the binaries if your prefer.
The download is available from root9.net
New build up – based on a git clone as of 2nd September 2012.
NOTE: The image itself works fine but I had problems accessing any online videos (tested with youtube and wired.com add-ons. Maybe I was just unlucky?). Could well be the network I was testing on though so please drop a comment if your build works ok!
