Advertisements My TivoHD box is connected to TW cable in Corpus Christi TX with SA cable cards. For the last couple of weeks it's had the pixelation issue, but I must say it doesn't appear as bad as some others have indicated, in fact on some HD channels it doesn't happen at all. Back to the new issue, it seems sometime during this week my TivoHD reports no or very low signal when tuning to channels 1-99, sometimes they appear for a few seconds then freeze (with pixelation) then the message appears. Sometimes they don't tune at all before the message appears. This happens when trying either tuner, but doesn't happen at all for the digital channels or the HD channels, only channels 1-99. My signal was tested at this outlet when the cards were installed and he said it was perfect, and this didn't appear for the few couple of weeks. Anybody else having a similar issue? Any thoughts on this issue?
