Script Summary: Download the movie trailers from apple.com, even with the new trailer page. The script has to be used in conjunction with HeaderControl to use the Quicktime User Agent string.
This script is an identical copy of the awesome Apple Trailer Download script by zatic (http://userscripts.org/scripts/show/2484). This script only adds a fix that will allow trailer download again with the new trailer pages.
NB: You will need to uninstall the original Apple Movie Trailers script before installing this one, to prevent conflict, unfortunately. If zatic updates his script, then I will take this one down. Credit for the original script goes to zatic.
For a while I was recommending people no longer use this script but use zatic's original script instead. This is no longer the case. Zatic's script doesn't work on the newer trailer pages whereas this one does.
