Advertisements Interesting cable card question for the community. About six months ago I moved my TiVo to a new location in my home. On Jan 1 channels like HBO, CNN, etc stopped working and reported they were not authorized. I called Comcast and they tried to send multiple signals to the card to reauth it and nothing worked. I called TiVo and they confirmed by going through the cable card settings that it didn’t look like the card was communicating properly with Comcast. So I replaced the card and no change with all the typical pairing, etc. A guy from Comcast told me I should try moving my TiVo to another location which I thought was silly, but it turned out he was right. I moved back to the old location, the card was reauthorized, the stations returned and I moved back to the prior location where I couldn’t get it to work. So it looks like the cable card required some periodic reauth to function correctly. Jan 1st seemed to be the date the cards “Expired” for me. Anyone know how that works? Is the auth configured on the card to expire on certain dates? To only last for a certain period of time?
