Apple’s Darwin, looking for the setup

I’ve just ‘installed’ via my Dreamhost hosting service, a Darwin Quicktime streaming server and I can’t seem to find the right combination of settings to get my movies from iMovie and working on the server space.

Using export functions within iMovie and then uploading to my directory via Filezilla, I’ve attempted to export with both .mov formats and .mp4 formats, I’ve selected the ‘streaming’ box when exporting in .mp4 and still I’ve found nothing to work.  The error I receive once I open the site and quicktime automatically launches is that I’m attempting to play an “unsupported media type.”  Drat.  !  Thoughts?
