 Duplicate detection with descriptions method work mostly very well.
 However, a series has been aired and I've recorded all the shows. Now it
 is shown again and for this particular series, the duplicate detection
 does not work for any of the episodes.

 Following shows one current example episode in current program info and in
 old recorded:
 {{{
 mysql> select * from program where description like 'Erikoinen suhde
 2/2%'; select * from oldrecorded where description like 'Erikoinen suhde
 2/2%';

 I've verified from the DB that descriptions are identical, with following
 query:
 {{{
 mysql>  select * from oldrecorded where description = (select description
 from program where description like 'Erikoinen suhde 2/2%');
 +--------+---------------------+---------------------+----------------+----------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+----------+-----------+--------+----------+---------+---------+-----------+-----------+------------+---------+

 +--------+---------------------+---------------------+----------------+----------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+----------+-----------+--------+----------+---------+---------+-----------+-----------+------------+---------+
 }}}

 Following shows the backend scheduling print containing this episode:
 {{{
 --- print list start ---
 Title - Subtitle                Ch Station Day Start  End   S C I  T N
 Pri
 ...
 Murhan jäljet                     1 YLE TV1 12 23:30-00:21  1 3 3  A 3
 18/0
 ...
 ---  print list end  ---
 }}}

 I've noticed that if I manually change the ''duplicate'' field in  in
 oldrecorded from 0 to 1, then (naturally) dupdetection works.

 I can do some debugging on my own but would need some guidance where to
 look etc. This issue would be easier to fix sooner than later since right
 now this particular series causes this problem to show up.
