[mythtv-users] Myth won't scheduling multi-part episodes

[ffrr]

I am trying to get it to always record Doctor Who.  Each showing is a 30 
minute part of an episode, that normally spans 4 of these 30 minute 
showings.   Each 30 minute part shows up in the guide with the same name

e.g.

Doctor Who -  "State of Decay"


No matter what I do with the auto-scheduling, it always schedules the 
first one, but not the later ones.  If I force it to record a later one 
('record anyway') manually, it turns off the earlier one, saying there 
is a later showing.

I thought the 'Record anytime on any channel' option should just do it, 
but apparently it refuses to record (what it thinks are) repeats.  How 
do I get around this?
