Are you getting this channel in SD over the satellite? If so the problem may be with a change made by the station to their OTA signal's PSIP data stream. while Dish receivers do not use PSIP for guide data, it does use a part of it for channel identification.
Have you tried deleting the OTA channel from your DVR and then rescanning it back into the guide? If not try it and then do a check switch to force a new download of the EPG. You may be pleasantly surprised.
I am receiving the SD channel over the satellite. I also asked the station director about any changes a while back, he said nothing has been changed, and that Dish should be receiving their OTA guide data. Now that I know the terminology, I may bring it up again.
As for deleting the channel, I cleared all OTA channels twice, have also run a check-switch...and replaced my receiver due to the inevitable "622 reset cycle" issue. Still says "digital service" for the OTA channels from that station... Bummer.
Thanks for your response, much appreciated.
