What can I look at to find out if this is what is actually happening?

You always like to blame the outside data source for issues... but the
reality is that the scheduler just isn't very smart.  It shouldn't be
that difficult to handle this situation properly.  Handling updated
scheduling information intelligently should be done regardless of the

8:00 -> 8:29 starts - > input X, channel Y.

8:01 -> 8:30 shows up.  input X, channel Y.

oh, look.  I'm already recording that.  Let me just record it until
8:30, instead of 8:29.  That would be the smart thing to do.

Of course, then again, I'm complaining about the scheduler that can't
figure out that DST happens twice a year, and completely hoses itself
every time that switch happens.  Guess I shouldn't expect much here
