Nothing on that page talks about one show being scheduled by two
different scheduling rules which is what was catching me out.

If the two schedules on the one show were treated as two seperate
shows in the scheduler then the logic on that page would do the right
thing, except for the fact that the show might be recorded twice.  I
guess the myth developers (and I'll admit to not having looked at the
code) decided to simplify things by using the "When two schedules
match the same program, the more specific rule generally wins
regardless of the priorities" rule.

It isn't a very common problem because it is hard to make schedules
that cause trouble like this without using the power search, and most
people don't run multiple schedules for the same show.
