Twitter hurting my backlinking?

[Kasru]

I've been using addmefast for twitter retweets lately for some of my youtube video links. Problem is my videos have gone from being near page 3 to page 5. While other peoples videos with no views are ranking front page. I am unsure if these types of backlinks are just hurting my page rank? Or do I need a lot more variety to stay near the front page?
