Modulation is NULL and should be qam_64 if Constellation is correct and
your cableco is using qam_64, otherwise both should probably be qam_256.
And sistandard should be 'atsc' for North American cable.
And are you sure about the frequency standard you used to scan with? A
frequency of 711625000 is not a straight US-Cable frequency but one of
the others IRC or HTC...You might want to try scanning with a different
set of choices on the Scanning Setup page:
And all of the above is wrong if you are not in North America! But
dorksville is in Georgia isn't it? ;-)
