No joke I get a TiVo message everyday that my Comcast line up has changed. Often is keeps changing the same channels. It has been going in for at least 6 months going back into 2011. Example HBO --> HBOHD then the next day will be: HB0HD --> HBO Then day after that. HBO --> HBOHD And keeps going, except maybe it will switch from HBO to TNT and keep changing TNT for a while. I called TiVo and asked 2-3 times, and get same response "Its not TiVo's fault because we simply issue changes that are given to us by Comcast". When I call Comcast, they point the finger at TiVo saying that Comcast is not changing the lineup, and say HBO (or whatever) has not changed, thus its a TiVo problem. Clearly this an automated process, which is failing, but both sides deny that there is a problem, or that if there is a problem, its not their problem to fix. Sounds like a sequel to the very funny movie: "Office Space". Any ideas what is really going on? . .
