Sorry, this is not true in the US. For the former use case, there is the First Sale Doctrine, which allows you to sell, display, or otherwise dispose of any legally obtained item. This is what makes libraries and video rentals possible. If you want to rent your DVDs to your friends, you are 100% legally entitled to do so.
For the second use case, there is an entire section of copyright law [Title 17, Section 110(1)] providing for classroom exemptions. You are allowed to show any legally obtained copy to students in a classroom enrolled in that particular class. Showing it to a full assembly or to a school club for fun is not allowed under this exemption, but may be a Fair Use under certain circumstances.
Fair Use may also apply in terms of copying materials depending on what it’s being used for, if you’re profiting from it, if it affects the market for the item, and so forth. Fair Use, however, is a legal defense that may be used in a courtroom, not a blanket exemption. The only way to prove a use is “fair” is to have a judge rule on that particular use.
When you copy a library DVD and/or bypass the encryption, you
might be breaking the law under the Digital Millennium Copyright Act depending on who you are and what you are using the copy for.
The rules change every three years!
But as with all copyright law, it’s more a matter of risk assessment. You
might be breaking the law, you
might attract notice from the copyright holder, they
might send you a takedown notice or cease and desist notice, they
might take you to court, they
might win. Think of it as speeding or jaywalking. Yes, it’s illegal, but you’re probably going to get away with it unless you’re really causing a problem.
Issues of license agreements or what is
ethical are each entirely different matters from copyright.
