best torrent network for documentaries?

Hey all, I was looking for a good torrent site for documentaries.. mininova.org is pretty good but one with a raito would be better for me.. I like to share and I like the better download speeds..

Thanks

(must register to use mvgroup, but its way worth it)

www.uknova.com has lots of good UK documentaries.

You have to sign up and they have a user limit so you may have to wait till theres an opening, but it's well worth it.
