I plan on switching to Dish Network from D* I am making the move mostly for the HD benefits on Dish. Anyway, can someone advise what type of questions I should ask the installer to make sure I get this installed correctly the first time? I have a HD ready TV and plan on upgrading that in the future. I have been told I should still see a great difference in the pictures. I am signing up for HD Platinume with local channels. I did not have HD on D*. I am getting the vip622 DVR receiver on one TV and the regular DVR receiver on another TV. I live the Chicago area. Any advice would be great and appreciated.
