After re-scanning and downloading the program guide, everything is back to "normal". NO PSIP data is being used in the guide, IMO. No offense to the DIRT team, but this is out of their realm. There's a thread with about missing guide data that has, so far, no resolutions...
DIRT has, in the past, attempted to research answer fairly simple "technical" matters such as why a DVR may behave a certain way by design. They have contacted Engineering and relayed the response for such easy matters. So, they have proven that such a request is within "their realm", and if is NOT, they say so. When DIRT doesn't respond to a direct request or question, it usually means the word is NOT to even venture a post saying "Sorry, out of my realm" as it is a subject Dish just doesn't want to address.
Listen, I LOVE the DIRT folks, but Charlie signs their checks and they want to keep their jobs, so I'm not upset that they have to ignore on occasion, but my point is that DIRT always responds with something, even if it is with an apology for something they can't do or provide, so when DIRT is SILENT, it really is a "shot heard 'round the world", the opera singer who cracks the high C, a huge noise of silence when they choose not to respond. I still love you DIRT and don't want you unemployed; I understand the silence.
The thread for OTA Digital Service you've referred to, Hall, has become a big dead-end joke (several posts make this point) with DIRT at first very integral to the thread to now being missing in action with no changes noticeable to the OTA data and no more dialogue with DIRT . If that thread were to be deleted, no loss of any helpful information.
