Digital Workshop

Having just discovered how a Flex pub can be used to launch a swf video and control it, i.e. play - pause - reset , I would value the ability to have the Flex flash act as a preloader for the called flash video - at the moment it seems the preload function only works on the Flex flash, not the launched flash, if that makes any sense.
So the called flash must load completely before my controls begin to work and there is no option for preload process bar or 'cogs' to indicate loading delay..
Perhaps I am missing something, of course!
