I have done my homework but did not see a simple fix.
I have loaded a 3 sec FLV movie with a black background to my index.html page using Dreamweaver and set the movie to start automatically. The index.html page has a black background to match the background of the FLV movie. 1 sec or so before the logo plays you see a "very distracting" white box (blank screen) where the flash player opens (surrounded by black). Once it opens all is well.
I have searched the fourm and see similar questions but did not see an answer...
