Bit of a strange one this. But you can get an easy dofollow link from Youtube like this using the following code:
http://www.youtube.com/redirect?q=http://www.markrushworth.com&event=as_seen_on_redirect&usg=-WBdJDUIh3qzq2EVUK7Z7SiyNDo=
Just change my website address for yours.
…now if i could now get an internal Youtube link to reference this that would be amazing…anyone any thoughts on this?

you can get a dofollow link fom youtube by putting the website in your profile info.
then just build up the pr of your channel!
Wow, yes it is actually is a one way link. I use the SEO book app with Mozilla and it has seems the link is dofollow! The method suggested by Mikis does not create a dofollow link. The question is how you could get this dofollow indexed. Will it help page rank just by clicking on the redirect link?
