I'm not sure who to report that to, but the underlying problem is that shared stations no longer have their own TSID and now have the same TSID of the host channel. So Dish needs to update their OTA guide data to use the TSID of the host station. The challenge though is that the FCC's database doesn't reflect this in their TSID listings, and going by the FCC's site alone to figure out which stations already migrated isn't going to help since they already changed the RF numbers and shared status for stations that will be sharing as soon as they filed who they entered into a sharing deal with. So Dish would have to do this on a station by station basis instead of relying on the data from the FCC
i.e. locally WVIA started sharing with WNEP back in December, the FCC's data reflects the channel 50 for WVIA, but it still shows the seperate TSIDs:
WNEP, RF 50 TSID 2519
WVIA, RF 50 TSID 2525 -- actually putting out WNEP's TSID 2519
Compare that to WWSI and the FCC already changed their data to show RF 34, even though they won't start sharing with WCAU until March since NBCU has a policy where there's no engineering work on any of their O&O's in the lead up to and during the Olympics to minimize the chances of the stations being off air or having to operate at reduced power if something goes wrong or the work gets delayed for any reason:
WCAU, RF 34, TSID 2491
WWSI, RF 34, TSID 1999 -- actually still on RF 49
As for mwdxer's issue, it's not an OTA issue. It's somewhat complicated to explain, basically MeTV's owners Weigel purchased KFFV and KVOS and moved the MeTV affiliation from KVOS (who's signal originates at the Canadian border and was only available north of Seattle) to KFFV (who's signal is based in Seattle)
Prior to a few days ago this was KFFV's setup for their first 2 subchannels:
.1 Evine Live
.2 Azteca
Now it switched to this:
.1 MeTV
.2 Movies!
What Dish (and DirecTV) carried on channel 45 in Seattle prior to a few days ago was Azteca via the .2 feed of KFFV, now they switched to carrying MeTV via KFFV's main channel, so they have to adjust their guide data for channel 45 to use the listings for the main KFFV channel instead of the listings for their .2 channel.
