My decision to leave comcast behind was because of there lack of support of cable cards for tivo. Numerous times i called and had trucks say they fixed the problem only to have it return. I finally got someone to fix the problem but only lasted for 4 months and the one set went south. So here i am looking into getting dtv i like the whole home box with a hddvr in the bedroom with athe wireless operation. My problem is that i have a lot of trees around the house so does the dish have to be in the line of site to the sat. or can it be up a little for reception. Do you get a 30day trail period to if it doesn't work money back? Thanks
