My equipment: HR44-700 C41-500 x2 HR21-100 HR22-100 x2 HR24-100 x3 Currently one 4K capable TV. Currently, my HR44 genie is connected to my 4K TV. DirecTV told me they could upgrade me to 4K at no cost. My understanding is that I would need to get a HR54 and a 4K mini. HR54 would need to go on a different TV and the mini would have to feed the 4K TV. They asked me what receiver I would like replace with the new mini. The C41’s I have now are both wall mounted and I don’t want to put the HR54 on one of those TVs. So which DVR should I replace HR21 or HR22 or does it really matter. Or should I just pay the extra $6/month and not lose 2 tuners by giving up a DVR? That probably doesn’t make sense, because I probably don’t need all 17 tuners anyway! . Just tough to give them up.... Also, it it good to upgrade from the HR44 to the HR54? Is there enough 4K out there? Are there other benefits? Thanks in advance for your advice.
