True, but unlike stationary (paper based) media in order for a user to "pre-view" an audio or video file they have to "see" multiple portions of the file. With traditional media I read a paragraph or an abstract and say this article is going to be worth reading let me download it. but with video I am going to want to see if it is relevant or if the quality is good enough. So I am going to want a preview function as a user. YouTube offers this feature where a user can start viewing the file from any point. For the system to load a full size preview and then for the user to not download it seems wasteful in terms of bandwidth. H.264 has a great scalable features. http://en.wikipedia.org/wiki/H.264 So why not automatically create a "preview" version when ever an audio/video file is added to the archive? Sure. There may be people who want the MPEG-2 file but there are people that will be served the file who don't want that original file. Why not serve them an h.264 preview of the file and then also serve them a link to the MPEG-2 file. Just like flikr.com gives users size options when they download pictures why not give users a size option when downloading video/audio/ pictures in d-space? - Hugh Paterson III
