Mediacomponents skinning!

I really need help quicky! I have a very short time left to complete my project.

I have flash mx 2004 Professional and i am using the MediaComponents for video playback.

I want to change the skin, however, i found out you can’t do it. CAN YOU use the MediaComponents.fla in First Run/ComponentFLA?

Can i change all the graphics in it and use it? In this file where will i upload the video/music file into? OR where can i put a address to the file.
