Probably same callsign, too (or instead--i'd go with the xmltvid
reported for the channel on the SD website).
Note, also, that as long as it's not a generic episode, the subtitle and
description will almost never have an effect on duplicate matching
(because with SD you get good programid's--which are always used as a
definitive identification scheme regardless of the specified dup
matching criteria). The only time subtitle and description come into
play is when you have "garbage" data that's missing programid--i.e. from
using another non-DD grabber (i.e. something other than SD or the TMS
DataDirect predecessor to SD), such as the "I'm too cheap to pay $20 a
year, so I'll use garbage data from some scraper" interim approaches
someone might have used. (I can't tell what you had before "moving to
Schedules Direct some time back.") And, anytime you switch listings
data providers, you basically give up duplicate matching against all
previously-recorded episodes because the descriptions and possibly
subtitles will differ--at the least, you give up accurate duplicate
matching. (Note, also, that SD and DD are the same provider).
And, in the event that the episode /is/ a generic, it will be recorded
on /every/ different channel and/or every timeslot on which it airs
because--by definition--it's impossible to determine if you've already
seen a generic episode. Note that when I say, "on every different
channel," I mean for every callsign (i.e. you tell Myth two different
channels are "the same" by assigning the same callsign).
