Can laserdiscs have Macrovision?
Apparently no. First of all, it is technically difficult, because the region used by Macrovision is also used to hold control data for the laserdisc players. Secondly, because of backward compatibility, the laserdisc specs cannot be easily changed. Thirdly, as long as the laserdisc market stays as a niche market, the distributors will not pressure the manufacturers to change the specs. And if they did, the sales would surely drop.
