I just bought a new house with a old Dish in the back yard. i have a old reciever someone gave me also. are these things still working? can i use it if i figure out how to hook it up? There use to be some kind of liscence thing you had to buy for them or something every few months to get feed. Is it still like that and if so where would i get it? or should i look for a hack or something for the reciever?
