Hi

I'm desparate to remove an annoying small blue speaker which shows for a split second at the start of a video i have embedded on a power point page.

It is a MPEG-4 movie and the movie launches automatically nice and fine as planned but the blue speaker icon flashes up at start.

Any ideas how i could remove?

It doesn't show on the movie when i play independently so its not part of the movie?

Thanks in advance?>
