Just took delivery of my new Tablo 4-tuner and am having some issues with guide data.
I think I’ve narrowed it down to an issue with the guide data provider, as several of the US-based channels are missing from the guide listings on zap2it.com as well. I’ve reported the issue via their feedback link, not sure if you have another way to escalate guide data issues.
For anyone else having this issue, you can use US zip code 14174 as an alternate which has all of the Buffalo and Toronto-area channels listed properly.
Hopefully this gets fixed by the guide data provider.
