The xmltvid will be filled in by mythfilldatabase. I suspect the
import parts are
the callsign and the channel number. Those have to match what the cable provider
has it listed as in schedulesdirect. For example, I have Charter in
Glendale CA. KCETHD
is channel 786 in schedulesdirect. But the ATSC virtual channel is 2.1
and the actual
frequency is 88.401. For the listing to work right the channel editor
has to show that
channel as 786 and the callsign to be KCETDT. But the channel
frequency has to be
88. The entry in the channel table has to have the right ATSC major
and minor channels.
Oh what tangled webs we weave. But the xmltvid will be filled in by
the right value if all of that is filled in correctly (especially the
callsign and the channel in
the first screen dialog of the channel editor for that channel).
