The case I've seen is for shows where they don't get the listings right
all the time.  I think this is a case where it could be even
more accurate than the normal "Sub & Desc."  This example isn't directly
from the program table, but it's an example of ways I've seen the same exact
episode referred to.  Title for all would be "Monster Garage", the
rest is mostly made up.  Think of an example of a show that comes on quite
a few times during the week and gets cycled often.  Keep in mind these
are all (fictional) airings of the same episode.

With Even If Empty, I get 3 dups of the same show after the original airing.
With the other methods, I get many more.  I think Even If Empty will get
the least number of duplicates in certain situations.

This is a worst-case scenario that could happen over a couple month or more
period, but it can/does happen.  The Even If Empty setting wouldn't be
necessary for most shows, but there are ones I record that look similar to
the above example.  I don't know if it's because of bad data or if they
just don't know what they'll air sometimes.
