The TiVo device is posting an eror mesage C133: There is a problem with the connection to the TiVo Service. Things will be back to normal shortly. (this was 5 days ago!,and it continues). "You can still watch live tv, recordings, and On Demand. Updates at Status.tivo.com."
Have removed and replaced card, jiggled anything I could reach,and checked TiVo and Comcast help websites. Please advise.
