I can asure you that Macrovision is carried through the "Y" Components output of the "Y", "Pb, "
Pr" signals. I have done many experiments with this.
If you need a way to filter out Macrovision from components outputs, the Video Filter is the only device in the market that I know of, which allows you do do this.
Sine I can't post sites for devices that do this on this forum, according to the moderator, you can write to me at [email address removed] and I will then point you to the website.
