I am really confused when it comes to this copyright issue. I am looking for an answer but have not found anything yet.

The situation:
I have a site with external links to youtube videos.

The problem is:
I am not always sure if the person that uploaded the video is the rightful owner.

If the disclaimer of the video states:
1) I do not own the rights to this song.
2) It is mainly for educational purposes.
(Is it still ok for me to link to these videos)

I am worried that if i link to these youtube videos that i might violate copyright.
I don't want to break any copyright laws and i don't want to go to prison.

If i added on my site a disclaimer that states that, i link to a song from youtube and that i am not responsible for whether the content is pirated or not.
Would this make it legal or not?

I looked at BBC - http://www.bbc.co.uk/help/web/links/
This is how they deal with external links. If i did something similar would it help?

Thanks in advance
