My guru buddy was telling me that in the Vista OS you must have the DRM capable Burner/player, video card, and monitor to burn and play Bluray or HD-DVD. This is old news.
New News---Vista DRM monitors all of your video files for DRM protection and if you try to burn a protected DRM video file Vista will disable your hardware drivers. It will also send the data to Microsoft that you are a nasty person doing illegal stuff. I hope this is not just baloney or inuendo. He said this is the newest info from Microsoft.
