Overnight, I lost all 99% of channels between 2 - 682. Tried troubleshooting; but no luck. I have two Tivo boxes -- both have the same issue. The one CV box I have is only an SD box, so those channels still come in (2, 4, 7, 358, etc.) When I go to them on the TiVo though, I get a "Channel not Available" -- its all very bizarre! Anyone figure out a workaround for this? Or, is it time to bite the bullet and head to the Amazon Firestick?
