The Youtube playlist have a xml strema, RSS feed.
You can parse this and create post via wp_insert_post()
and add as content the URL to the video. Publish this and you have wich each new video from the playlist a new post.
The best way is, that you write a custom plugin. But you can aslo use a auto publisher plugin for feeds.
