Alright, I have some questions on how the whole satellite tv thing works through directv. When you sign up with them, they provide a receiver, the dish, and the cables and stuff. In the receiver is a.. smart card? right? What determines if your paying for your satellite TV package? Is it based on the actual satellite or the card inside the receiver? If you were to change packages, would they send you a new card, decrypting the new channels you are purchasing?
