External F4V Playback Issues - Newbie

Question

First off, I'm a hobbyist and very new to Flash and script.
I have a project that I want to install on the end user's
local Hard Drive via CD. The project consists of multiple swf files
running via a Flash Player 10 Projector. There are multiple F4V
movie files imported in through Flash CS4 via the Import Movie
function with Playback Component. I don't have any script added for
the external movies. The project works great on my local hard
drive. However, when I burn these files to a CD for playback with
an autorun or build them into an installation .exe file that
installs via autorun on the end user's hard drive, several of the
F4V movies don't run. Embedding the movies is not an option because
they are decent size and would slow down the project. Also would
lose quality going to FLV. Maybe script is needed somewhere but I
thought the Import Movie function did this instead of adding
script. Clearly the different location for the files is causing a
problem. Thanks for any help you can offer!

Thank you for the reply.
I followed your suggestions and added a preloader to this SWF. The preloader works great outside of Captivate, but is totally ignored when I incorporate it into my Captivate project. The same behavior occurs (audio only plays while loading, then video begins after 10 seconds).
I created the SWF in SwishMax by adding the preloader to Scene 1 and proceeding to the content on Scene 2 when the loading is complete. I suppose I can build a similar test SWF in Flash itself, but I fear this will be a waste of time.
Any ideas on why the preloader is being ignored or another approach to loading this external SWF?

BTW: Code for the preloader is here:
onFrame (5) { 
    if (sceneFrameLoaded("<last scene>",-1)) {
        nextSceneAndPlay();
onFrame (8) {
    percentLoaded.txt = "Loading - " add getPercentLoaded() add "%Complete"
    bytesTotal.text = Math.round(getBytesLoaded() / 1000) add "KB out of " add Math.round(getBytesTotal() / 1000) add "KB Loaded"
    loaderBar._xscale = getPercentLoaded();
    if (getPercentLoaded() >=99){
     nextSceneAndPlay();  
onFrame (9) {
     prevFrameAndPlay();
