An anonymous reader writes "In the last few weeks the first HD-DVD and Blu-Ray drives for PCs have slowly trickled onto the market. Up to now, it has not been clear what system requirements you need to actually be able to play HD-DVD and Blu-Ray discs. The operating system was the main cause of concern; many rumors cropped up that the new generation of video discs would not work under Windows XP. Hardware.Info put the question to Cyberlink, the company behind Power DVD, if the lack of a protected videopath in Windows XP would make it impossible to enable HD-DVD or Blu-Ray playback. They have answered the questions, and provide a complete checklist of what you need to play Blu-Ray and HD-DVD movies in HD resolutions on your home PC."
