People have a right to record a broadcast and watch it later. This is known as 'time shifting'. See https://en.wikipedia.org/wiki/Time_shifting https://en.wikipedia.org/wiki/Time_shifting . In "the Betamax case" - Sony Corp. of America v. Universal City Studios, Inc. - the Supreme Court said that time shifting was fair use as it did not substantially harm the copyright holder or reduce the market. Selling the recorded video takes it outside of that definition of fair use.
