I just bought a new 4K TV that is Directv ready. I now have 2 HR 24-100's with an AM-21 on each. I know I need a new Genie and a Genie Mini. Will they work with the AM-21? If I keep one of the HR24's, will it communicate the the Genie for whole home viewing? I have to decide if it's worth it to not loose all my recorded shows. Thanks
