As it should. I have bookmarking of movies allowed.
I'm stopping hotlinking not bookmarking a movie, but a simple change to my htaccess would also prevent this.
This line in my htacess allows bookmarking a movie or pic.
RewriteCond %{HTTP_REFERER} !^$
Try pasting the url of the movie into this page and you will see that it does not play.
