The other thing is: it's one thing to have a bunch of relatively obscure subchannels that are available OTA that show up in the guide without any data, and it's another to have one or more of the 5 major networks in a DMA have channels mapped to numbers that were last correct 5 years ago, with missing or incorrect program data.
For example, my OTA adapter scans around 72 channels. My Dish-provided locals total 17 channels. Two out of the five major networks (PBS and Fox) have absolutely zero guide data for the primary channel as half-heartedly provided by the OTA guide listings. I'm not asking for every little CoziTV, QVC, Buzzr, Bounce, StarTV, Grit, Laff, Ion, Rewind, ShopTV, AceTV, etc., subchannel. It's not unreasonable to expect proper listings and channel mappings for CBS, NBC, ABC, Fox, PBS, and I guess The CW to be in place for each DMA.
If you're in the TV business, as Dish is, and have enabled and sold OTA adapters to allow users to use antennas with their Hoppers, and integrate these channels into the Dish guide, then you should step up, own, and fix the many guide problems. It would also be reasonable to expect that the Dish team that apparently sporadically monitors this forum to step forward and help own the issues as well.
