hi, there is a flash movie in header on hbo.com/biglove/index.html

before the movie is played you can see the underlying background and color changes on mouseover.

I would love to achieve the same functionality on my client's site. how is this done? does flash player has to this functionality? If yes, is there any player which provides this feature?

the restriction is that my movie file is mov.

i realize that this is default picture before the movie is played. the client already has a player which supports mov file so is there a way to find out which flashvars are supported by it so that I can set the picture?
