Around 2001 I purchased 6 DVDs of Sex in the City to watch on my computer and was unable to play them, because MacroVision required software DVD players to ensure the return value of a function called "AnalogTVOut" was set to disabled, but my particular video card did not have an analog TV output, and hence this function could not be disabled, even though the video was not capable of playing video to any external device. The vendor had not mentioned this on the support site for my video card, but it was mentioned in the support forums once the problem appeared and I knew to look for it. In the end, I had to buy a television set and a DVD player, since I did not own either, just to watch six DVDs I had legally purchased.
