Adobe Acrobat X.
Content / media in the "Select a file or enter a URL-address ..."
and press OK
Get a message "Do not specify any single media file".
I think it's saying you have to give the URL of a movie .That isn't a movie, it's a web page which shows a movie. Youtube's movies aren't intended for use as single media files, they want people to visit Youtube (and see the adverts).
Acrobat XI's changes in the sandbox and player decoupling broke it, sorry.
