[mythtv-users] Scheduler crazymaking

[David Hampton]

I'm using v0.25.3 as packaged by atrpms for Fedora.  My setup contains a
HDHomeRun Prime with six tuners and two Fios cable cards.  I have one
video source defined for Fios, and all six tuners are connected to that
video source.  None of the card inputs have a priority associated with
them, nor do any of the channels, nor do any of the recordings.

  mysql> SELECT sourceid,name FROM videosource;
  +----------+--------------+
  | sourceid | name         |
  +----------+--------------+
  |        1 | Verizon Fios |
  +----------+--------------+
  1 row in set (0.00 sec)
  mysql> SELECT * FROM cardinput WHERE sourceid!=1;
  Empty set (0.00 sec)

  mysql> SELECT * FROM cardinput WHERE recpriority!=0;
  Empty set (0.00 sec)
  mysql> SELECT * FROM channel WHERE recpriority!=0;
  Empty set (0.00 sec)
  mysql> SELECT * FROM record WHERE recpriority!=0;
  Empty set (0.00 sec)

Even so, mythtv insists that there is a scheduling conflict between two
shows: Castle and Defiance.  It decides that on the 22nd, Defiance at
21:00-22:00 conflicts with Castle at 22:01-23:00.  It decides to record
Castle, bump Defiance til later, and leave five tuners sitting idle.
Oddly enough, the following week the tv listings are the same but mythtv
decides that it can record both of these shows using the same tuner.
(Possibly because the reruns of that episode of Defiance don't yet show
in the listings?)  I've posted the output of 'mythbackend --printsched'
to http://www.dhampton.net/mythtv-schedule.txt (instead of including it
inline since its 475 lines long).  The only other thing I can think of
that might be relevant is that I have both the global preroll and
overrecord settings set to 120 second, as the networks seems to be
playing with show start times.

My question is why anything is getting bumped when I have six identical
tuners to choose from when recording?  If any more information is needed
to help figure this out, please let me know.
