IIUC this partitions duplicate matching, such that duplicates would be
found for repeats on channels whose metadata comes from the same source,
but still not for repeats that span listings data sources. In order to
achieve that I believe (but do correct me if I'm wrong) that I need to
continue erasing the programids.

It would have caught the specific example I gave though, since it seems
that the three showings of Escape from Alcatraz were (in one case will
be) broadcast by the very same channel.

Thanks, Jan
