Hi Dave, I actually work with correctional facilities that show movies over their cc channel or in the day rooms. I don't want to get into a sales pitch or anything, but a lot of facilities find that by using movies mixed in with educational films their viewership goes up. You can also control the content you show and the times movies air to fit in your schedule. Let me know if you'd like more info.
Thanks! Erin
