one show known by more than one name

I was just perusing my guide here and I noticed that there are instances
where one show can go by more than one name. Case point:

Orpah Winfrey
The Oprah Winfrey Show

(Everyone says it but really, this *is* the wife's show -- not mine)

Both appear to have the same SD prefix as the two episodes I have on
hand here are:

EP000032413949
EP000032413950

It would appear that as far as recording rules are concerned, these are
not the same show -- one is scheduled to record, the other is not. I'd
swear however that two of the 3 episodes that were scheduled to record
today got whittled down to one when I did a mythfilldatabase to update
today's data. I suspect that pulling in today's data changed the show
Title of two of the three, as I now only show the one as being scheduled
to record.

Is there any support in the database and scheduler for this kind of
"alias" show name? I wonder at least, if you were to have both names in
your recording rules if the repeat/duplication detection would work
across them given that they seem to share common episode identifiers.

Cheers,
b.

This has other ugly side effects, like if you wanted to limit the number
of recordings of that show, no matter which name it was recorded by, you
can't, it would seem. :-(

Just use a single custom/power recording rule for these corner cases and
it solves all the problems. Use the "Match words in the title" example.

OK. That solves the episode limit problem. But how does such a
recording rule work out duplicate/repeats? By matching Title and
Subtitle, so that the same Subtitle for an "Oprah Winfrey" show and an
"The Oprah Winfrey Show" are not considered the same? For Schedules
Direct where there is a Program ID, is that use in conjunction to or
instead of Title/Subtitle?

Title is always a factor in duplicate matching. If a show is
retroactively renamed, it will break duplicate matching--but in such a
way that you re-record episodes (so false negatives--which are
recoverable by just deleting the extra episodes, or marking them to
Never Record when you realize you've seen them, or using a recording
rule that only records new episodes or something). Then again, if it
was an actual title change (like the one for NCIS, which removed the
periods), maybe TMS will always use the proper "historical" name for the
old episodes.

As I thought.

Indeed. Not the worst of the possibilities.

Given that at least once source of scheduling information (SD) provides
a "unique id" type of field which appears (in this case at least, so
perhaps for all intents and purposes) to be independent of cosmetic
metadata such as episode titles, subtitles and descriptions, wouldn't it
be useful to provide that as a duplicate matching option?

Or is the Program ID not as useful in this regard as I am imagining it
is?

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.

See, also,
http://www.gossamer-threads.com/lists/mythtv/users/169129#169129 for a
much better description of the issues than I could provide. (Note that
seriesid is the "SD prefix" you mentioned.)
