Advertisements Reposted form Bolt/Roamio forums ↑ Reposted from Roamio sub forum [Hi within the past two weeks, I have been getting intermittent freezing followed by a v58 error (channel not authorized). I called the cable company (Optimum) and they send a new signal to the Cable card, I replaced the cable card, but the problem still happens. It does not happening as much on the Roamio Pro Plus that I have, but on the mini it happens a lot. The cable company said that the TiVo is the issue. Does anyone else have any ideas?] I am having the same issue on a Tivo Bolt, as well as my Roamio and Mini. I also have had no luck after numerous attempts by Optimum to fix it. Hopefully, someone at Tivo will see this chime in.
