Video Tutorials page not displayed

I installed the Integrated Video Tutorials plugin on my site and added my site to the Registered Domains list. The videos show in the Contextual Help but not for the options Dashboard and Top Level. Am I missing something here? I also tried installing the WPMU DEV Dashboard plugin thinking I might need that to fully activate the videos plugin but no difference.

Also, how can I turn off the “install the free WPMU DEV Dashboard plugin” nag without installing the plugin? I’m planning on installing the Video Tutorials plugin on a client site and don’t want any mention of WPMU DEV.
