Quick question on publish settings

I am increasingly seeing flash movies that fill up the whol epage irregadles of the size of the monitor.

I notice this quite a bit since i use a 1600X1200 resolution

what are the setting use to get the backround of the movie to scale, but keep the actual contents of the movei [buttons, graphics, content areas] from scalling

example
www.blackpulp.com
some graphics run all the way to the end of the screen, while others like the content areas that load up. always stay the smae size. Plus things like the meny that do run to the end of the screen, dont actually strech they just show more of the graphic…

even looking at the source has not given me much information, how do you guy setup your movies
