Perhaps having realised that going out of one's way to inconvenience customers is not a good business model,
Hollywood may be giving up on Macrovision, the copy-denial mechanism that prevents you from connecting a DVD player to a VCR. Warner Home Video have released the Harry Potter DVD without Macrovision encoding in the UK; this means that you can plug your DVD player into your VCR and pirate it for all your friends untrammeled. Or, if you have an older TV without A/V inputs, you can plug your DVD in through your VCR and watch it, full stop. Mind you, Macrovision costs the studios a few cents per disc, and is fairly easy to bypass with (as yet not illegal) "signal enhancers".
Macrovision also interferes with video projectors. With more and more people having home cinema installations, it must be a problem.
