From what I remember In canada what they do is pick up signal leakage from the junction boxes and all of the connectors you use to connect things. all they have to do is drive down the street with a sterio antenna and watch the signals peak and fall. The Coax acts like a big antenna, and the cable companies know how much TV you have licenced and how much a normal house with normally degraded cabling should leak, anything more than that and they get suspicious. An easy way to foil that is to leterally foil each of your connections. and to make sure you are running new cable. Wrap each junction in alumininum foil and tape(duct or electrical) and away you go each junction will leak lessdo two layers of aluminum and you get better, but dont go over nuts. So usually you can attach two mre TV's than usual. As far as satellite some of our companies (bell) can send a signal through that activates your decoder box. If the signal they send doesent match what you card is preproggrammed for it zaps the card and you have to call to get it reprogrammed, call more than three times and they will not do it because you are ovbiously piriating. Yet more reasons whay it is better to program a 486 to decode than to use the card.
