Then the show that's not recording because it's recording on another 
channel is recording on another channel at some other time or you didn't 
create the right type of recording rule (i.e. it's a find one instead of 
a "any time" rule).

To tell you exactly what's happening, I'd need you to post the 
(complete) output of mythbackend --printsched 2>&1 | tee 
$HOME/mythtv-schedule.txt (i.e. attach ~/mythtv-schedule.txt after 
running that command) and tell me exactly which shows (title/subtitle 
and start time) you're interested in.
