A couple of years ago I "moved" to a zip code that qualified for DNS. I have 2 HR10-250's with the HD package and have been receiving HD distant networks and SD locals. This weekend I'm installing a slimline 5 lnb dish and have a HR20 on order. When I activate the HR20, will I be able to keep my HD DNS for the HR10-250's and receive HD locals with the HR20?
