FLVPlayback Seekbar Handle issue

So I’ve coded together a video player using AS3 and use some custom UI components. The video plays an intro vid, feature, and an outro vid–then loops. I move the seekbar movieclip off the stage during the intro and outro vids but it’s still there and when viewing the swf, you can see it’s still working–just out of view of an embedded swf.

Everything works fine and perfect on my local machine but when I upload the files to a server, the seekbar handle doesn’t display on the seekbar unless the flv file is already cached. If you watch the video (thus, caching it) then reload the page, the seekbar handle works perfectly. Any idea why the handle isn’t appearing for a video that’s still downloading?
