If the OP can let us know how he has confirmed that the PSIP is now being used by the DVR. Several OTA multiplex channels do have accurate guide data, but it is because of what Dish has finally gotten and send via Sat as part of the LIL EPG data, NOT PSIP. I think there is a misunderstanding. I still have a lot of the same "Digital Service" even for ones that are easy and for which PSIP does have such as PBS World, but NOT on my Dish 722 or 722K.
Dish and TiVo use Tribune for EPG (TiVo does NOT use PSIP). TiVo has accurate guide data for all but one of my OTA multiplexed while Dish still have nearly 20+ channels with "Digital Guide". Perhaps such complete OTA guide data is an enhanced service by Tribune that Dish won't pay for.
Question to the DIRT: Considering both TiVo and Dish contract with Tribune for EPG, why does TiVo have nearly 100% full EPG data for ALL OTA's while Dish has far too many "Digital Service" displaying in the guide? AND understanding Dish requires subscription to LIL's to receive OTA EPG, why doesn't Dish just activate the PSIP for the multiplex, at least, as people would still be required to subscribe to LIL?
I don't think we will get a decent answer, but it is worth a try.
