There are two different issues. There is the normal question of
which of two different titles has higher priority and thus which
title gets recorded. However, in this case we have two rules that
match the same showing of the same title. Here the question is
which rule controls that showing.

For instance, say you have an All rule for a favorite show with +6.
Due to circumstance you want it to record on card 2 tonight and can
do so by lowering the priority to -2 so you add an override. If
the controlling rule was chosen by priority, the override would lose.
An override applies to a single showing of a program that is also
controlled by a recurring rule. The override must always win precedence
in order to work. The same would be true if you set a kWeekslotRecord
rule for one showing where you knew the time was always off by a few
minutes and a kChannelRecord for all other showings. The weekslot
rule needs to control that specific day and time over the more general
rule regardless of any of the recording parameters.

In the code, this decision is made by RecTypePriority().
