When you import any movie to Flash, if the codec of the original is supported, it converts it to Flash video format, .flv.
So the FLV is now "embedded" in the swf, is this correct? Are you using any pre-built video player features in building the swf? Often the prebuilt objects have class files or support .swf's that need to be uploaded with the video player.
I suspect it's more related to plugin version or deployment methods in the errant computers, though. Try exporting copies of the SWF, but modify the Flash Player version in the publish options - that is, see if it will export for Flash player version 7 or 8, be sure to save as a different-named copy.
