Switching off video side bar on a group by group basis?

Hi SI Team

I love 2.1
But have a couple of minor problems this is one of them.
I know that I can switch videos on and off for a group.
If I switch them off for a group then the group just does not have video period.

But lets say I want to display videos in a Group.
But do not want people to be able to add videos.

The idea of this group is that I the teacher post videos for the students to watch.

I do not want the students posting videos in the group.

Can we figure out a way to hide the video side bar on a group by group basis?
