The only way I know to automatically generate a playlist of all videos from an uploader is adding "&list=UL" at the end of url of any video from the uploader.
Usually I can copy a playlist into my account by entering the url of it at this website called "Copy YouTube Playlists" : http://ctrlq.org/youtube/playlists/
But it doesn't work for playlists generated by adding "&list=UL" to the url. The website "Copy YouTube Playlists" would say : "Sorry but we could not find that playlist on YouTube. Please entire a valid YouTube Playlist URL."
Could anyone please tell me how to automatically create a playlist in my account which contains all videos from an uploader? Thank you!
