I just wasted an hour + of my life. I decided to try tivo one more time. I explained the problem and was told that they are receiving other calls regarding the same problem. He set up a three way call with comcast. The first two people we spoke to had no clues and said they really don't support the tivo feature and to call tivo. I told him that tivo was already on the line. The tivo agent asked to be transferred to a higher level of support. After a 1/2 hour of being on hold the tivo agent had to leave. I waited another five minutes and then hung up. Comcast only answer was for a truck roll. I told them no as it is not a hardware problem on my end. The tivo agent supported me. Anyway after all this I am no better off. There does not seem to be any way of getting someone to fix this. I love my tivos but sometimes there is a big prolem when both tivo and comcast are pointing fingers at each other. I hope someone else in this thread gets better results and we can piggyback off their solution. If it gets solved it will be on this forum. I guess I can live without on demand. I wonder if I am entitled to a discount on my bill if comcast cannot fix the problem. I also wonder if the app was accidently corrupted during the daily download from tivo. Who knows. My guess is as good as their's.
