Here is my setup first. Directv came and setup a 5LNB dish 2 months ago. They installed HD DVR at no charge and I had 2 regular box also. I want to get another HDTV. Would there be any issue if I get an open box H20 receiver w/card of ebay? Would the receiver be consider mine or still there and I'm leasing it like a new box. Am I stuck with a 2 years contract once I activate it? I guess I would need to buy a switch also, because all 4 lines are being used now. Thanks for your help.
