ONE OF the 'features' touted on the new Microsoft Vista (nee Longhorn) operating system is the Protected Video Path - Output Protection Management (PVP-OPM). Nick Farrell does an excellent job outlining it here.
In a nutshell, unless you have a display device that is equipped with specific technology intended to foil recording, the operating system will degrade the image quality so bit for bit copies cannot be made. Sounds good, right? Well, considering that almost NO monitors are currently shipping with this technology, it means that if you want to view a movie off a HD-DVD as it is encoded, or stream HD content from a Blue-Ray disk to a display, the operating system will kill the video outputs and give you nothing. If you are lucky enough, like me, to have a projector that can handle RGB signals or DVI inputs, you can get a signal but it will be run through a downscaler then an upscaler to reduce the quality.
