Suddenly none of the movie players, which previously worked, will start DVD movies. Windows Media Player puts up a notice that Copyright Protection is the cause. Nothing has been changed otherwise. The drive is found, and the name of the movie is recognized. DVDs which previously worked were tried.
I haven't gotten into this sort of thing before, so I'm wondering whether the Copyright Protection reading/validation is done within the DVD drive, in the MPEG-2 codec, in the video card hardware, or where?
