Yes, I am in the US, using over the air antennas receiving ATSC broadcasts.
If I look at my options in mythtvbackendsetup, they are "Full Scan", "Import existing scan", "Scan of all existing transports",
and "Scan of single existing transport". I'm not sure what they mean by "transport" I assume that would correspond to a channel
and sub-channel. What I want to scan is an arbitrary channel, not an "existing transport" I accidentally deleted the transport,
so it is no longer existing.
There is no tool tip for the "Scan Type", so I must judge by the name what it does. I tried scanning a single existing
transport. It scanned channel 2. There was no option for me to specify which channel to scan.
So if a new station appears, the only way to add that new station is to do a full scan, and then go and edit every single
channel again.
Just to give you an idea of the scale of the problem, here are my three video source channel listings:
