I am looking to a direct tv receiver that would be able to do a partial zoom.I currently have the Dish network and their 6000 model.I find that zoom modes degrade picture quality and stretch modes just don't look right.I really believe that Dish networks picture quality is getting worse and from what I hear Direct Tv excels in both picture quality and menus.I just want to be able to have the partial zoom option if i make the jump to Direct tv.
