I just purchased the Tivo Roamio and the mini. I have everything in a closet av rack downstairs of my home. All my devices are in this rack including these 2 new Tivos. I ran a 100' HDMI cable from my downstairs to my upstairs bedroom and was working perfectly fine with my cable box a couple of days ago. That same cable, I cannot get signal on my Mini. My question is, do I need an HDMI extender/booster to get a signal off the 100' HDMI cable? The Tivo mini works because I tested it with the 6' HDMI cable in came with. Thanks!
