Customising slides to get rid of menu

while still taking use of the full size of the slide. How is this done?

In my Project I am doing a software demo and then feel it would be great to be able to use the full size of the slide, so I customised those specific slide and great I no longer  saw the menu.

However the swf or also MP4 that I have used does not fill up the window as I had hoped, instead I see grey background around the swf and MP4 files.

I would like my swf and Mp4 to fill up the whole content area, is this possible?

(I tried to resize the swf on the slide but that did not work I still got the grey areas around the file)

see my example below.

 Thanks!

Looking forward on your response!
