In the very simple example, showing how to Instantiate and Configure the FLVPlayback component, there was one crucial line of code missing:

myFLVPlaybk.source = “examplevideo.flv”

In this example, we’re pointing to an FLV in the same directory as your SWF, called examplevideo.flv. If you don’t specify a source, your FLVPlayback component won’t know which video to play.
