The HD DVD format has got an extra anti-piracy boost with the help of a new audio based watermarking technology, unveiled by the Hollywood. The technology works by adding a watermark to the soundtracks of all major movies, including those released at the cinema. This watermark is not audible to the human ear, but can be recognised by the decoder in HD DVD players. If the HD DVD player recognises the watermark that should not be present on any HD DVD media (such as the watermark included in the soundtrack in the cinema), it will stop playback of the disc. The same goes with detecting a watermark on recordable HD DVD media that should only be present on original factory-pressed media.
In order to prevent a mess-up from happening, such as if someone accidentally captures the sound of a movie while taping with their camcorder, the HD DVD player allows a certain amount of tolerance. This means that for clips of a short duration, the HD DVD player will not reject the movie, such as from someone taping the family and happens to have a TV on with a HD DVD movie playing in the background. Unfortunately in an aim to enforce this anti-piracy measure, Hollywood aims to have this anti-piracy measure implemented in all recordable drives including (but not limited to) CD/DVD drives, hard disk drives to even PCs.

If they wanted to stop a lot of dvd piracy they get rid of that rediculous zoning of discs. If I want to buy a cheaper dvd from abroad than they want to sell me over here I should be able to do so without having to spend alot of money on a multi-region dvd player which may or may not be able to read the disc.
Myself I'd never buy a pirate copy, not out of principle but because I am a sound and vision nazi and pirate copies tend to be crappy. I can wait for the prices to drop...
