Hey Guy's ...I just wanted to know of an easy device or circuit I could
build myself..not to cause a heated discussion.. Thanks

I built one many years ago from an R-E article. I'll tell you which issue
number when I find it. I dunno if it'll work on PAL systems, but it's a
good source of info on Macrovision anyway.

But there's some newer versions of Macrovision that dork around with
the color/colour burst reference. Elektor had an article on it
two or three years ago, and it looked nasty.
