This is total nonsense. I have talked to TV stations that send the correct guide info out and yet it sends up wrong on the Dish OTA guide. I have been fighting to get my guides right for a year now. The information is correct but not connected to the channel.
In other words, Our ABC (KATU) has a PBS guide, CBS (KOIN), another different PBS station guide, NBC (KGW), the FOX guide, PBS (KOPB) a ION guide. No guide on FOX (KPTV) or MYTV (KPDX). I finally bought a Amazon ReCast with a free 2 week guide. The guide is totally accurate on all stations including sub channels. Somewhere the info Dish gets is all mixed up and with several tries, I have never got it corrected.
