May I suggest disabling auto-focus on the camera? It was a little distracting.
Also you might want to use some of the LMCE terminology, like "on-screen orbiter". Just simple like, "and here we display the on screen orbiter which lets you control the LMCE system..." Your target is the uninitiated, so dropping some of the basic terminology with show and tell definitions may help.
You might want to mention that there are other supported orbiters than the fiire.
Maybe add a title screen with www.linuxmce.org
