Anyone know for sure? > >Dave Downin\ Check out the May 1990 issue of Radio-Electronics for a neat project that will restore the sync signals (horizontal AND vertical) to a wide variety of sources. There is also some discussion of methods of scrambling video. This project will allow MacroVision to be defeated, as well as the scrambling technique used on direct satellite transmissions, and that from the local cable company (I speak of the non-sound-distorting method!). I haven't built it yet, but I will. It should be interesting! It's called the Universal Descrambler! Hehehe... Mark C. Lowe - KB5III
