Up until about 3 months ago my tivo was working fine with the cable card. Then we started seeing pixelation on our HD channels. It got to the point that we could not watch the hd channels. Then we noticed multiple regular channels receiving the v52 error. At this point we have not had complete service through ore tivo for about 3 months. I have called tivo, they say it's a signal strength issue. I have called Comcast. Tried re-pairing card exchanged card- tried pairing. I have attached an hd converter box to the tv directly to check signal and cords. Works perfect with the hd converter. We have restarted the tivo multiple times. Performed the guided set up multiple times. Tried the tivo on a different tv and nothing seems to help. Have spoken to multiple reps on the phone. None able to get it working. Sounds like a common problem and I wish someone could fix this. I haven't been able to record anything or watch any hd in the past month with the tivo.
