Not sure what you mean here.
TMO no longer exists, so you can't upload to LH website any longer.
There are, however, a lot of sites around which enable you to upload your movies; Youtube, Vimeo, Veoh, BlipTV to name but a few. And there is, of course, TMUnderground.
Machinima maker? Using The Movies? iClone? Moviestorm? Any other engine? Then check out TMUnderground at (http://www.tmunderground.com/)
