I had a failed demonstration when speaking at the Microsoft Management Summit - it pains me!  As I promised, I have posted a video of the demonstration working as it should have.   You can find the videos at CSI-Windows.com or at YouTube.com/CSIWindows.  YouTube lets you play at full screen, and since these are HD videos, that option may actually be useful to you.
