OK, there are and there will be more videos about PD on youtube and 
colleagues. The problem is not to organize PD contents on youtube, 
this monopolistic video vacuum-cleaner, but to organize the links to 
the youtube/dailymotion etc. PD videos to find the right video at the 
right time.
Some solutions:
-create a "video links" page on the official puredata.info wiki, with 
categories index, links and descriptions of each film +tag about the 
language of the video.
-create an international "video links" page on pdpedia wiki, with 
categories index,  links and descriptions of each film+tag about the 
language of the video.
but I would prefer:
-Install a PDmotion video server, exempted from advertising, ( 
Oggvorbis/theora/icecast or Red5 driven ), and use PDpedia.
