I have an older HR21-100 and just got a new 4K Samsung TV. (I do not care about the 4K but the picture quality was best for our price point). When we connected the TV, sat 2 in (error 771) appeared. After snugging up the connections to the DVR and B-band converters, I got signal back. Then I moved the DVR 1/2" over and lost sat 2 again and cannot get it back. I called DTV and they need to do a service call. Should I ask for new HD-DVR and if so, which one? This one is in the bedroom and the only thing attached to it is internet and the TV. There's also a BluRay attached to TV but this is all relatively low tech as it's for TV watching before bed. The kicker is that the DVR is in a closet so we need an RF remote. We have the current DTV RF remote but it is sooo slow- even with new batteries. Can I keep this remote with a new DVR? Can the old remote be sped up somehow to reduce lag time? Which HD-DVR: HR24 or Genie? Our other DVR is an HR-24 in our family room. It does the bulk of our TV watching and is connected to a home theater system, Apple TV and gaming devices. We use a Harmony remote with this TV and components (all hidden in media closet) and it works great. We are 12+ year customers of DTV (if that matters). Thanks!
