I just filed a complaint with the FCC. I encourage everyone in the WPMI broadcast area to also file a complaint:
FCC Consumer Complaints
Your complaint makes no sense in this case. WPMI is DT47 and WJTC is DT45. WPMI has the main (sometimes HD) feed and NBC Weather Plus. WJTC has just the main feed.That WPMI is broadcasting two HD networks on the bandwidth allocated for one HD channel and a couple of SD channels.
Quite a few stations are doing the double HD on one ATSC. They usually downrez the 1080 to 720 then throw it in a statmux. Looks like crap but better than SD.
