For 7 years we use Tivo Roamio Plus with 2 minis. Everything worked great. Then yesterday I installed the new Edge for cable, activated etc. Then I tried to transfer movies from Roamio to Edge which did not work. Apparently group information is missing now on both. So, we wanted to switch back using our old Roamio and the Minis via Moca network. The Roamio Plus works fine but the Minis don't. Network connection process works all fine and I can see the Roamio Plus but it is grayed out and I get a message saying that it can't connect V70. I spent 4 hours on the phone with Tivo tech support going thru all kinds of settings and restarting. At then end the tech support person said that I use the wrong cable splitter. I have a 5-1002 MHz but I need a 2000 MHz splitter. Can that be? Everything worked fine until 2 days ago. The problem started when I installed the Edge. I really wonder why the splitter should be the problem suddenly.
