Resizing flash projectors

I’m having a few problems with flash projectors.

I want to be able to put my finished site onto CD and launch it that way. The problem is I want my main movie to always be 824x602 but the background to resize to fit 100% of the screen.

when I try to do it it either scales everything to 100% so all my images looked stretched or it doesn’t scale the background and I’m left with half the screen being white.

Could anyone point me in the right direction or provide a sample I could work with?

Thanks for your help.
