Line 82 needs to be updated to include another class - found from http://userscripts.org/scripts/show/57184
var nobjects = xpath(document, "//a[@class='large' or @class='small' or @class='medium' or @class='hd' or @class='target-quicktimeplayer']");

Line 151 needs to be updated to replace trailers. with www. - I discovered and tested this about 5 mins prior to this post.
url_default = url_default.replace(/(movies|trailers)\./, 'www.');

Many thanks, it works. After so many months, I am able to see what I wanted. 2nd, I still can not download the HD versions of the trailers with this.

Looks like they changed something again. If you install an agent switcher (http://userscripts.org/topics/33557) you can change the agent, then right click on the HD button you want, and "Save As".

The script still does not work with the latest apple trailers. For example: http://trailers.apple.com/trailers/paramount/th...

I installed the addon 'User agent switcher' and used the preset: http://userscripts.org/topics/33557)
But when i disable greasemonkey and swith the user agent to apple trailers and right click on the HD button and "Save As" it start download the trailer: http://trailers.apple.com/trailers/lions_gate/k...
So the conclusion is that the Apple Trailers script seems to do nothing.
