I remember the "big" dish. We had one when I was younger in the late 70's early 80's. We lived in the country and got ONE channel. When we first got the dish nothing was scrambled, and we got everything. After a few years, a few channels were scrambled, until all but the religious channels were scrambled. Then came the chipped receivers. They worked for a while, then you would have to constantly change them out. Then you could hook up a PC and get the signal. It was such a circle jerk. We finally got cable, and the old dish is still out there ( I think even the old receivers are around my dad's place somewhere, but who knows (he passed away in 2002).
Today, it's not worth it. You can still "steal" the signal if you want, but you really have to be clever. You still need a PC, some Linux software, and the right stuff, but it's not worth it.
I guess I say all that to say this. It use to be OK, wink, wink, until it wasn't. Once they got people hooked they started cracking down on piracy. - and no I don't condone it.
