I need to upgrade a standard receiver to an hd receiver and want to know what is the best way to go about doing it. I already have an hd dvr in the living room and would like to replace a standard for an hd receiver. If I call directv about it will they automatically renew my contract for 2 years for the swap of receivers? I don't really wanna leave directv but don't like their practices about an upgrade causing a 2 year extension either and especially in this market we have today. But I guess if theres no other way than I just have to go through with it.
