I really don’t understand most of this message. What do you mean by “Zero on their channels updates, downloads.”
Have you tried running another channel scan to see if these stations show up? Are you in favorites and you’re not seeing a guide? Can you share a picture of what you mean by any of this?
I’m not sure if it helps, but I ran a channel scan and everything (main channel, sub channel) is showing up as it should.
I rescanned my Tablo a few days ago and found 74 channels including ABC,CBS,NBC. and FOX. The next day I noticed that ABC,CBS, NBC, and FOX were no longer on the guide. What is going on?
