If both episodes have a program ID, that is used as the definitive
identifier of the episode (i.e. user-specified duplicate-matching method
is ignored). That said, the scheduler /only/ matches duplicates where
titles match--otherwise, in theory, they're not the same show,
regardless of program ID.
Besides, for XMLTV users, we often make up program ID's and nothing
would prevent duplicate program ID's across different show titles, so we
can't just change it.

much better description of the issues than I could provide. (Note that
seriesid is the "SD prefix" you mentioned.)
