and -, compare this to the channel listed in the Tune column for that channel in HDHomeRun Setup, and uncheck the ones that don’t match. If you mouse over the different sources, it will show you at the bottom the channel number it is on.
In WMC, you’ll see all the different sources you have for each channel. To correct the situation, go into Tasks > Settings > TV > Guide > Edit Channels > affected channel > Edit Sources. If it guesses wrong, the channel will not work. WMC isn’t smart enough to know which one(s) you can receive, so it adds both, then guesses which one to use. In short, this issue occurs because these stations are/were transmitting on more than one channel in your region, either because of a channel change, or because of translator stations that are used to serve nearby towns that can’t receive the primary transmission due to terrain.
