How to make tutorial videos viewable by role?

I have IVT installed, but thus far as SuperAdmin, I am the only one who can view them. How can I make it so that our Editors, and Authors can view them. Also, I'm using the User Role Editor for a custom role called "correspondent." None of our users (except a test acct) are set up for it yet, but I'd prefer to use it and would like to know how to grant IVT permissions in it, as I havent seen the IVT listed yet as an option to grant access to it.
