I've seen this happen before.  I missed an episode of Invasion.  The 
show was on the schedule, but got removed when the scheduler was getting 
run and re-run while recording other shows that preceded Invasion.

I really think it's related to #1319 ( 
http://svn.mythtv.org/trac/ticket/1319 although it may not be the same 
problem) as #1319 is a "temporary" condition.  Basically, #1319 seems to 
occur when mythfilldatabase replaces a previously-scheduled program in 
the listings with a different program.  By re-running the scheduler 
(mythbackend --resched) you can fix it--it will then realize not to 
record the new (non-matching) program.

The same applies to the problem you've seen (except that it's not due to 
data being replaced in the listings).  If you were to have noticed that 
Grey's got removed from your schedule while recording other shows that 
night, you could have run "mythbackend --resched" and it would have 
re-appeared in the schedule.  I've done this before when another program 
was removed from the schedule.

Don't know if it's a race condition, but it's definitely unpredictable.  
I've spent a bit of time trying to track it down, but didn't have any 
breakthroughs...

Hope David Engel sees this...  :)
