Just replaced 722k and I can't get it to accept both TV1 IR and TV2 UHF remotes in single mode , It worked before but I forgot to photo SYS INFO. Have 10 remote tv's on TV1, no Hopper hype please but any help will be appreciated.
IR worked but not UHF , but your comment had me try it again and I found the remote RF ant (8' coax) connector had come apart , fixed it . Thanks !!!!!
