I am having a problem since I got my Mini installed. Here is my setup: 1 - Living Room - TiVo Premiere 4 - Connected to the router via ethernet 2 - Bedroom - TiVo Mini - Connected to internet via MoCA I noticed that I get the "black" screen often in my main tv when I select a channel. I then go channel down or up a couple of times and then the channel shows up. I called my cable company, and had one of their cable card technicians come over. He spent two hours in my house. Everything was fine from Cox part, signal in my house, tuning adapter and cable card. He was getting 89 signal strength across the board. He mentioned that the problems comes from TiVo Mini since the Premiere 4 thinks that a tuner is busy because of Mini. Have you heard anything about this? Anybody experiences this? I am seriously thinking of returning my Mini and canceling the subscription, since this is driving me crazy. I have also missed a scheduled recording twice now, because of this problem. Thank you in advance!
