[mythtvnz] Scheduling conflict with multirec

[lists at whitehouse.org.nz]

Hello all,

I was looking through my conflicts and was surprised to see the following:

DVB0	Hell's Kitchen 
2 - TV2	Tue Jun 1, 2010 (07:28 PM)	1 hr 7 mins	

DVB1	Hitched 
3 - TV3	Tue Jun 1, 2010 (07:58 PM)	37 mins	

Conflict	♦♦♦House: The Choice 
3 - TV3	Tue Jun 1, 2010 (08:28 PM)	1 hr 7 mins	

DVB0	HD♦♦♦The Good Wife: Doubt 
3 - TV3	Tue Jun 1, 2010 (09:28 PM)	1 hr 7 mins	

DVB1	True Stories: Real Wolf Kids 
9 - PRIME	Tue Jun 1, 2010 (09:33 PM)	1 hr 7 mins	


(I swear that the shows listed don't truly-represent my taste in
television!) I have a dual-tuner DVB-T card with four multirec tuners for
each real tuner. 

I just added the Wolf Kids programme (hangs head in shame) now. None of
the shows are set to record on a particular tuner.

If nothing else, it should be able to record all TV3 programmes on the
same tuner and then record Hell's Kitchen and Wolf Kids on the other one
(these don't overlap).

Can anyone suggest why the scheduling seems to have failed here before I
manually fix it up? Is there some command that redoes the scheduling/tuner
allocation? Is scheduling fixed up as part of mythfilldatabase (ie, if I
leave this, would it fix itself up)?

I haven't had any issues with scheduling before, so am keen to get to the
bottom of this before I fix it.

Thanks in advance,

Aaron
