Showing videos as a general rule is a Performance Right issue, not Fair Use. The DMVs in my part of the world routinely broke the law by showing Disney VHS tapes in the lobby. I'm talking for years, not just an isolated incident. That's not a Fair Use issue in the least, and lawyers, with respect to the law, could reasonably pursue compensation.
Are you familiar with "independent coffee shops" coming under fire from ASCAP for hosting open mic nights and/or playing AM/FM/XM/Internet Radio without paying official dues? The poor widdle coffee shop owners claimed it was extortion, or they tried to muddy the water with some kind of Fair Use claim, but they didn't have a case and I have to admit that ASCAP was abiding by their legal rights. Now, coffee shops are more diligent in telling people to play originals, not cover songs.
Overall, my point is that Fair Use is so utterly abused as an argument by people who don't understand Copyright, Performance, and other nuances of (wholly butchered / Disney-lobbied) legal channels that it genuinely hurts those who understand the concept. I routinely have to counter the argument that Weird Al is an example of Fair Use (as a general principle of using other people's music) because it's a very specific issue that he is legally allowed to do - Parody. Showing Bambi or non-Public Domain documentaries in the lobby of your library isn't Parody, nor should it be argued that way. Besides, if librarians can't find enough Public Domain content or educate students enough to assist them researching a project, then the job is effectively wasted space, and should be tossed out of conversation with respect to utility and necessity.
So your recommendation to all the street performers? If open mics are "stealing" from the artist then street performers are at a whole new level. We will have no art or performance in our society if we continue these down these roads of copy right and performance.
Only one's that can do anything reflecting to society will be satire and that is only because of the Supreme Court.
What you're failing to recognize is that the coffee shop owners are, for lack of a better term, profiting from the music being played in their establishment. In a more direct case I can speak to, I frequently purchase beer from the places where I've played open mics. They directly profit from hosting the event, and feel that they should be exempt from paying the compositing artist association dues...why?
Now, for street performers, they are providing a service akin to radio, insofar that they are publicising a song, not charging a cover, and further advancing the arts and society's respect for them (putting aside the quality of the performer). That's why my local city has ordinances actively supporting busking - provided no solicitation for compensation is put forward - because it makes life better. In turn, performers are allowed to have a tip jar or accept compensation as they are benefitting society and the arts through the "practice and performance of their craft" as the ordinance describes it.
The Satire/Parody Distinction in Copyright and Trademark Law— Can Satire Ever Be a Fair Use?
Supreme Court also ruled that Satire/Parody is Fair use protected due to their verdict in Campbell v. AcuffRose Music, Inc

So don't touch and don't get near anything that looks beyond showing a video in the classroom. Then a school was sued for students watching legal videos in "public areas" AKA lobbies and even outside on their laptops. This was when buy these viewing licenses to cover yourself for classrooms that show video content started.
