Looks like Syncom decided not to renew affiliation on 1 January for H&I and Movies! (circumstances beyond our control). That is, the Weigel Broadcasting which owns H&I, Movies! and MeTV may have upped their carriage fees..
Maybe H&I and Movies! may end up on another Denver channel. But, KREG's signal will never make it to Denver. It is lucky it makes it to Aspen and Grand Junction, let alone Denver.
Finally, thanks to cell phones, and the FCC auction, we are seeing the beginning of reduction of digital subchannels. There is now less frequencies available for US broadcast TV. What used to be 81 channels, then 68 channels, is now down to 29 channels. (7 - 36). Though, some low power channels can run on 3 -6.
Denver has a crowded spectrum, but not as bad as a place like New York or Los Angeles, where there are a number of channels that will go dark, so people can get G5 cell phone service.
Also, if more main channels go from 720p to 1080i, then more subchannels will be eliminated.
Of course there is ATSC 3.0, which is being tested, that could reverse this trend.
