Thanks to both of you for letting me know that I do not need to wait to get terminators. I ended up having some time tonight to disconnect my HR20 and install and activate the HR44. I must offer a huge thank you both to those that directly posted answers to some questions that I had and to all other posters that are kind enough to take the time to offer assistance to the forum community. I have MRV so the HR20 that I replaced had the "special" set up with splitter and band filter and the install instructions that D* gives you are very generic and does not address the HR20 situation. The help offered here made for an easy Genie replacement install. It might be my imagination but I seem to have a much better picture with the HR44 than I had with the HR20. I also followed the suggestion to completely disconnect all cables from the HR20 before deactivating it and I can still access the recordings that are on there so success all around.
