We've been able to confirm that none of the Built-by-ATI Radeons support HDCP. If you've just spent $1000 on a pair of Radeon X1900 XT graphics cards expecting to be able to playback HD-DVD or Blu-Ray movies at 1920x1080 resolution in the future, you've just wasted your money.
NVIDIA, being a GPU manufacturer was unable to discuss the plans of board manufacturers. We contacted all six of NVIDIA's Tier-1 board partners. None of the GeForce 6 or 7 video cards available on the market, including the most recently released GeForce 7800GS, have HDCP support. So if you just spent $1500 on a pair of 7800GTX 512MB GPUs expecting to be able to play 1920x1080 HD-DVD or Blu-Ray movies in the future, you've just wasted your money.
Tech companies are effectively using DRM to block out other tech companies to gain more control. The licensing board for DVDs is involved in a lawsuit with Kaleidascape, a company that makes DVD jukeboxes (capable of storing about 660 movies) because the companies that sit on this board are most likely unhappy that a company is providing a better product that is obviously impressing consumers. That's an example of how this game is being played.
