I'm not sure the preloader will solve the issue...
The .swf is setup to load on the fifth frame. Will the
occupies the first two frames) account for a .loadMovie on
the fifth frame?
In case it helps, the loaded .swf file is a file which loads
file. So I have one main .swf file which loads child .swf
file (which in
turn loads an .flv file) on the fifth frame of the main .swf.
