Certain subscription services such as Netflix and Amazon include in their membership agreements that the films cannot be use in a class or shown in a public setting. This applies even if the face to face teaching exemption would be in effect.
If a club or organization is putting on an event that is educational in nature (such as having a discussion after the showing), it could fall under fair use.
Netflix, Hulu, iTunes, and Amazon Prime are all platforms available for streaming either as subscription services or as rental agencies. Most students will either have their own account or access to an account, so they would be able to watch a video class on their own time instead of being required to get the PPR to show it in a classroom setting.
