I was commissioned by a Melbourne media studio to create an xml-driven preloading flash video player and a simple mp3 player for the launch of the new Tennis Australia site.
The flash video needs the most recent version of flash and will play full screen mode. Commands are sent from javascript into flash using the ExternalInterface class. The mp3 player will send a stop playing command into the separate flash object also using the same protocol and vice versa.
Email me for any help on this still rather inadequately documented and fiddly and not particularly cross platform as you would like process!
