Hi, in summary, I have one TIVO bolt, one tivo mini on a moca network. My cable provider is comcast. Over the last year or two, I get tiling on certain stations, GOLF, HGTV and perhaps a few others. It is not constant but annoying enough that I have tried to fix several times. Lately some stations are unwatchable. Comcast says signal strength is fine, tivo says all settings and signals are fine as well. TIVO sent a replacement box but it was worse with that so will send another to see if that works. Over many months we have replaced all cables, went from a powered splitter to a standard splitter to one with 5-2500 MHz. Golf channel comes in without tiling via their box but when I use the tivo with cable card, the problem returns. I've read forums all over comcast and tivo, spoken with multiple people at each company, restarted my modem, cable box, tivo box a ridiculous amount of time. Does anyone know what I should do? I am almost to the point of getting a refund on my tivo membership and dropping cable completely, I am so frustrated. Thank you for any suggestions.
