However, the complaints from the group about importing the DVD concern the copy protection mechanisms on the disc, including Content Scrambling System (CSS) and Region Coding which is designed to ensure that DVDs can only be playable in certain regions of the world where they have been bought. Fortunately, mainly because of Norwegian hacker, Jon Lech Johansen, these restrictions can be removed from the DVDs making them viewable in other regions and you no longer are required to use a "licensed" DVD player.
Of course, Hollywood was and still is furious over DeCSS and other software as it means their control on importing DVDs from other countries can be beaten. However, use of DeCSS and other tools capable of circumventing copy protection mechanisms on DVDs is illegal in the United States due to the Digital Millennium Copyright Act (DMCA). So playing a legally purchased DVD on certain players in the world simply doesn't work due to the Region Coding, yet it is still illegal in the U.S. to remove copy protections from your legally purchased DVDs.
So in conclusion, this is simply a bunch of complaints that we hear at AfterDawn very frequently, but it's an interesting example of how copy protection puts unfair restrictions on consumers that Hollywood depends on to stay alive.
