Sorry this is a bit lengthy! We have recently switched from Verizon Fios to Optimum/Cablevision for a better internet connection (made the switch friday, only 4 days ago). I have a series 3 HD Tivo box in my room and I have been having issues. At first, I was only receiving "analog channels," (channels 2-22). A grey screen appeared and a message saying to call Optimum phone number to activate channels, I called, they said it's an issue on Tivo's end, everytime it updates, I will have to call to get my channels back. The gentleman over the phone only managed to restore about 10 more channels, so I had channels 2-32. Said it was an issue on the technician who did the install. On friday and saturday I had no issues, Sunday is when I started getting that error message. We scheduled a tech to come, but we'd be charged if it was Tivo's fault. I decided to turn it completely off, unplug it, and plug it back in. The error message popped up as it loaded back up, but then I had all of my channels back to normal. Now it is Tuesday, I have season passes for shows that run during the day (NCIS, Law & Order, etc.), I go to watch, and it's just a grey screen, 0 minutes were recorded. I go to watch live TV on one of the channels in the 30's, grey screen, no error message, just grey. Again, I restarted my Tivo box by unplugging and plugging it back in, and again, channels are back to normal. Has anyone had these problems or similar with Cablevision/Optimum? We're still in somewhat of a trial phase, we still have Verizon Fios router and cards, so we can still potentially switch back. Thanks so much!
