I suppose that selling is not necessary, distribution is. Record a movie off cable TV, share with your friends, and lo and behold, they're not going to buy the licensed VHS tape! And maybe even not going to subscribe to cable TV! Losses, losses everywhere.

Several years ago, I've read about a similar case somewhere in Europe (Germany?): a group of friends gathered together for a party, and it was either some show on the cable, or they blared some broadcasted music on the loudspeakers, or something, but somehow the police got involved, and the guy at whose house they've gathered was found guilty for illegal broadcasting/retransmission, because apparently, if more than 3 people (without familial bonds) watch the same TV or something like that, then yeah, it's broadcasting, and you need the license and the rights to the material.

I remember in 1980, when our school got a VCR and television (on a cart to allow it to be moved from one classroom to another). one of my teachers said that she wasn’t allowed to record something off the air at home and then show it in the classroom.
