[mythtv-users] Duplicate detection

[Jan Ceuleers]

Dear list,

I have multiple listings sources, in part because there is no single
listings source that has all of the data that I need. Each listings
source has its own program ID scheme, so I can't rely on program IDs for
duplicate checking, particularly of shows that might be broadcast on
multiple channels and therefore get to me via multiple listings sources
(such as movies).

I thought I had solved this problem by including the following in my
daily listings cleanup script:

# Force duplicate matching to rely on title, subtitle, description (or
whatever
# is set in the recording rule) by getting rid of program IDs which are not
# consistent between listings sources.
update program set programid="";

This gets executed after the mythfilldatabase --file runs (for each of
the listings sources) and is followed by a mythutil --resched.

The rule using which I record all movies has its duplicate check method
set to Subtitle.

Yet I still see duplicate movies in the upcoming recordings. For
example, I could have sworn that I recently watched and then deleted
(without "allow re-record") Escape from Alcatraz, but it is again going
to be recorded.

Can anyone suggest how I can further troubleshoot this? For example:

- how can I confirm that Escape from Alcatraz was indeed recently deleted?
- how do I double-confirm that the upcoming showing of this movie is
being recorded because of the recording rule that includes Subtitle as
its duplicate setting (although mythweb already says so)?
- any other troubleshooting steps you would recommend?

Many thanks, Jan
