Are you administrator in Moodle B? Can you go directly to the course in question? Then can you click on Users>Enrolled users and enrol the teacher with the teacher role?

You could put your video in a Page resource and that will work. And no; there is no way to ensure a student watches the whole video apart from asking them questions relating to certain elements of the middle and end of the video.
You can use Activity completion along with Conditional activities with this and use any course format.

For checking spelling, it is recommended to use an in-browser spell checker. Do you have one of these working?
