This playlist parser parses Youtube playlist links in format 'http://www.youtube.com/playlist?list=...'.
To get to the playlist page from a channel you must start playing the first video in the playlist and then click on the video's title.
Now you're on the normal youtube view with playlist bar on the bottom. To get to the playlist page you have to click on the playlist's name on the playlist bar.
Open the playlist page's url in VLC and it should automatically populate your VLC's playlist with the youtube videos.
