Has anyone else experienced this? Have a TiVo Mini connected via MoCA to a Roamio Pro and Time Warner digital cable. Watching recorded content works fine, but when I try to watch Live TV, certain channels will play for 2-3 seconds followed by some kind of error message that flashes on the screen for less than 0.1 seconds (so quickly I can't read what it says), and the picture freezes. It only happens on specific channels, which obviously makes viewing live content on those channels impossible. Any suggestions on how to fix this?
