Harry,

You don't have to do anything to the other columns.

Lets take 79#0 as an example.

We've discovered, via tuning it by some method (frontend or other 
utility), that it is NBC-DT for your area.

What I do in this case is the following via mythweb:

1) Change the xmltvid from blank to the correct value from my schedule 
provider
2) Change the channum to the channel number from my schedule provider 
(for the sake of illustration 79#0->4.1)
3) Change the call sign to the appropriate value (again, for the sake of 
illustration UNKOWN79#0->WBZ-DT)
4) Change the Frequency from 79 to the channel number from my schedule 
provider (79->804).

Save the changes.

In the case where the scan identifies the channel correctly, I need to 
only do steps 1 and 4 from above.
