Publishing to wp blog from in youtube channel?

YouTube has a setting to enter wp username, password, api and api url.

What this is supposed to do is connect your WP blog to yout youtube channel so you can publish your youtube video from your channel to the blog.

I keep encountering an error filling the youtube details:
An error has occurred. Message: Unknown

If you have a youtube channel you should be to get to what i’m describing here:
https://www.youtube.com/account#sharing/blogs

Other then that anyone know why it’s not working? I’ve tried the to way hosted and wp.com and various combinations but none work!!

This is the instructions in the settings:
Add a Blog / Site

Specific Blog Host Requirements:

* Friendster: Your username is your email address.
* WordPress.com: Requires your blog’s url (blogname.wordpress.com) if it is not username.wordpress.com.
* WordPress Self-Hosted: Requires an API key and the API URL (https://your blog’s URL/xmlrpc.php).

Blog Service:
