I have heard that you can raise events in Silverlight videos during playback, but I hadn't thought much about what I would do with it. Rob Blackwell shows off a particularly innovative use of this capability, encoding his video with GPS coordinates which are exposed through onMarkerReached events during playback. In the Event he grabs the coordinate and updates the Virtual Earth map accordingly.

You can try the application here. (click the London River Thames link, and then press the Bike Cam button)*And you can read some background from Rob on how he built it here.
