Hi all, I have read through several posts but can't find anyone that has the same issue I am having. I have a Tivo Roamio Plus with comcast. I have had it for about 3 months now. I had issues getting it setup and paired in the beginning but everything was fine until about a month ago. Randomly I would get the V58 channel not authorized message on all my channels. I would call comcast, they would send a signal and that normally fixed it. For the past month I've had to do this about 8 times. Today it happened again but this time the refresh signal didn't fix it. Of course we go through all the troubleshooting but nothing works so they want to send a tech out. I don't want to do this because I'm sure there is nothing a tech can do from here that a tech over the phone can't do. I've checked my signal levels and they are all fine and I have a comcast STB HD in the back that is working just fine. Has anyone else ever had this issue? I love my tivo but at this point I'm just about fed up with this (not blaming Tivo). Any help on this would be greatly appreciated. Thanks!!
