I continue to have cablecard issues between my HD Tivo and Comcast. It has been getting continually worse. Each time I change to a different channel the cablecard setup screen appears instructing me to press CLEAR. (This is after years of successful Tivo use first with a standard feed and now with HD) After I press CLEAR the appropriate channel appears. Comcast checked things on their end and they said the problem is with Tivo. Tivo instructed me to restart my machine and that if that didn't solve the issue it was Comcast's issue. Unless someone can help I think I will move to ATT's U-verse. (That way I don't have Comcast or Tivo thus removing whatever the problem is). Does anyone have an idea?
