They include a script that captures a few minutes of each QAM channel my card could tune into. Viewing these lets you identify the channels and write a channels.conf file. This can be imported into the Myth db using the channel scanner . . . "Import channels.conf" is one of the scan types.

Stefan:

Yes, I remember reading your note; however, at the time it seemed to
be inapplicable because I knew which captured channels mapped to which
channels on the OTA guide.  I'll go back and take another look, but
doesn't importing the data just write the information into the xmltvid
field of the channel table?  If so, that is what I've already done by
editing the database so I must be missing something else.

Thanks for reminding me of the post, though.  I'll go back and review
it again to see if there is anything I missed.
