Macrovision is clearly limited in what they can do and still be compatible with existing hardware players. With VCR copy protection their system depends on the receiving VCR to cooperate (recognize a macrovision code and block recording) with several schemes coded into the VCR from the start so they could put a new system in newly released movies after each old system had been cracked. If you have an old enough VCR, it is immune to all macrovision.
Back to comparing DVD drm to Apple, the fundamental difference is that you can buy any brand DVD player you want, and new companies are free to buy into the system to either produce disks or players.
