The answer to my own question is: The recording opportunities available 
on the DVB-T source have a subtly different "description" than the ones 
on the DVB-S source and this description matches a previously recorded 
one, so they are not available as candidates for scheduling. I have 
never found "description" useful for duplicate matching. Is there 
somewhere I can change the default from "subtitle and description" to 
"subtitle" rather having to remember to set it each time?
