I ran a query a few nights ago on my then-current 14-days of listings
for my Virgin TV video source in MythTV to count flagged repeats and
was quite surprised by the findings. This query was clearly automated
and I haven't checked the listings manually to look for mis-flagged
repeats (I'll add premiere/repeat counts to the grabber's debug
output).

The query was:

SELECT
  `channel`.`name` as "Channel",
  count(*) as "Programmes",
  count(nullif(`program`.`previouslyshown`,1)) as "Unknown",
  count(nullif(`program`.`previouslyshown`,0)) as "Repeats"
FROM
  `program`,`channel`
WHERE
  `program`.`chanid` = `channel`.`chanid` AND `channel`.`sourceid` = '2'
GROUP BY
  `program`.`chanid`
ORDER BY
  `program`.`chanid`;


The following channels (ignoring any timeshifted versions) provided no
repeat flagging at all:

Watch
GOLD
Dave
Alibi
Comedy Central
Syfy
5*
5USA
Universal
DMAX
Quest
Blighty
Eden
Discovery
Animal Planet
Disc History
Disc Science
Good Food
Home
Really
Disc Realtime
Disc Shed
Disc Home and Health
Sky Arts 1
MTV
VH1
TCM
Movies 24
Film4
Eurosport
Eurosport 2
BBC News
BBC Parliament

It's a bug in MythTV if it's using provided data incorrectly (or
worse, creating erroneous information when none is given). As Karl
mentioned, MythTV's listings infrastructure is heavily skewed toward
the TMS/Schedules Direct services and the very rich data they provide.
Other XMLTV sources - uk_rt included - do not provide such rich data.

Cheers,
Nick
