Just an update for anyone interested...
Janne on the dev list helped me with this. Based on the the "-v
channel,record,siparser" backend logs and the output of dvbsnoop, it
was apparent that the station wasn't broadcasting the PMT (Program Map
Table) in their MPEG transport stream:
I emailed WNJN about it and they corrected it.
