I have Comcast cable. For sometime now I have been having a problem which can be described as having the exact same technical problem as satellite "Rain Fade". On a limited set of channels, the signal strength drops to about 60%, and there is a digital break up of the picture\audio exactly like rain fade (its not compression pixilation). Nearly always its in the morning or afternoon hours between 7am - 3pm, and never at night. The pattern it is the same channels as far as I can determine, but I am not checking all 700 channels. Its not a block of channels, but rather a mix of isolated channels spread throughout 3-1000. Includes SD & HD, encrypted\Not encrypted, including the local NBC HD Station which is not encrypted. Even an HBO channel. Why would some channels be effected but not others? Example 701 is perfect, but 702 has 60% signal, 703 is perfect. Any explanation on why the same time every day (7am - 3pm)? I know that if I call Comcast and report the problem, they are going to suggest that I replace the S3 TiVo with one of their DVRs (always their default solution). I am not hater of Comcast, so I have no ax to grind with them.
