So I just called and got an upgrade to the Genie. I currently have 2 HR21s and they are going to be sending a Genie to replace the HR21 in my bedroom. They said that that I can just plug in my Genie to where my old HR21 is and it should be good to go. A few questions: Are there going to be any issues with this? Will I be able to record 7 shows at one time with the Genie and the HR21? Is there any benefit to having a Genie Mini instead of the HR21 in the other room? Thanks!
