I recently had a lot of problems with OpenElec and XBMC remote which I use extensively as a media player. Firstly the PI refused to even start but now that problem seems to have passed. Shortly after that problem passed the free XBMC remote I was using on the Nexus 7 would cause the whole system to crash. This often manifested itself in menus seemingly cycling through endlessly rather as if a button had stuck down. Since then I have moved to the free Yatse which even auto configures and this seems to solve the problem; I’ve not had time to fully test it yet but so far so good.
