You have to plan around this factor.  It may take lots of planning.  Use

TestMovie and Bandwidth Profiler to see how the movie will download under

real internet conditions, then reapportion content accordingly.  As for

what to load first, not to be snide, but load the stuff that will be viewed

first.  Using some math skills you can figure out, given typical internet

traffic, how much of something needs to preload in order for it not to

choke before the end is reached.  you can build in loops using If Frame Is

Loaded to hold up the main timeline while stuff loads in the background.

In these loops you can still have interesting content.  This is an enormous

area of challenge in Flash; if you're going to do serious, large Flash

projects you will need to work on how to plan around bandwidth and streaming.
