Getting started with the VideoDisplay control

I was experimenting with the VideoDisplay control the other day and built this simple little example to help me understand the order of events when loading a Flash Video (FLV).

The following example creates a VideoDisplay control and displays each event in a debugging DataGrid which displays the type of event, video state, playhead time, and total time of the FLV:
