works out of the box with raspbmc :)
great little remote, easy to program your tv remote into this. its a hybrid (hence the name) RF and IR remote. its uses RF to control xbmc and IR for your tv/other device, and you just switch between input methods (so you cant push volume up in xbmc to change volume on tv, you have to first swap to IR mode then volume).
and on the raspbmc side of things, menus are pretty fast now with the latest nightly builds. still room for improvement, most with large lists with posters, and when playing back video in the background.
but general use the menus arent slow (not super fast, but i wouldnt say slow either)
