If Dish still had the Tech Forum, matters like this would sometimes be addressed, often providing a good reason for the lack of whatever service or feature and a PUBLIC assurance they are working on it or even a clearly stating that it aint gonna happen, and at least we can move on from there.
IMHO, it is probably the sheer size of the guide data with all those sub-channels. They are probably trying to make it work, but we have no indication of how things are going or if they feel confident of a fix. Based on the response to the emails, it sounds like when the get complaints they move to provide it for that one area as an appeasement, short-term I believe, but we are in the dark on this, and that is not good. They should re-instate the Tech Forum or a new formatted Tech Q&A (to avoid promoting vaporware such as the Sling Extender) or something like it.
I would be THRILLED if they provided the guide data for the following sub-channels:
This TV
Antenna TV
ME TV
We still get Living Well HD guide data on our 7.2 and even 7.3 (in SD). We also get the STUUUPID NBC California Non-Stop channel guide data at 4.2 (tears of sadness to bid farewell to Universal Sports which was at 4.4 and always had accurate guide data). There is also a fair amount of guide date for the foreign language sub-channels and many others, but not all. Considering how popular Antenna, This, and ME TV are, one would think Dish would make that a priority.
Charlie seemed a bit more willing for Dish to be forthcoming with addressing flaws, but Joe doesn't seem so with other past flaws since his installation. I wouldn't mind a Joey Clayton Chat.
