[Papervision3D] PV3D 2.0 : VideoStreamMaterial Security sandbox violation

[Michael Cronin]

Whew ... thought I was missing out on something... visions of broken  
apps made my heart skip a few beats ;)

Some errors can be caused by trying to use the video stream before it  
is available so its good practice to use an event handler to check for  
loading problems and availability.
Otherwise I can report I have no problem using video materials with  
Great White with progressive download.
