Hello there,
as wrote in the last post, we got the Official XBMC release by Stephan Rafin. As well as the lsronga release this version has full graphic acceleration based on openGL ES 2.0 and can run HD videos very smoothly.
Here for the official thread where you’ll find the link to download the image for both the Quad and Dual version: https://www.udoo.org/forum/viewtopic.php?f=28&t=518
