Hi, I'm a long time Dish Network customer preparing to upgrade to HD. I am considering the 622 but really don't want the dvr service. I want the 2 tuner receiver though. If I own a 622, would Dish give me the option of not subscribing to dvr? I will probably buy one outright on eBay. If Dish requires the sub, I would just purchase a 211 and keep using a SD receiver on TV2. THANKS!!!
