If I recall (it's been awhile since I played with this) if it sees a
recording will end in say 15 minutes and isn't over it will add 5
minutes and reschedule.

This is probably what is going wrong.  I remember looking at the
record table and seeing many overrides corresponding to the recording
that was being extended.  But looking at the code it looks like it is
trying to do the right thing and just changing the endtime for single
and override rules:

         $rule = new RecordingRule($this->getVal('recordid'));
         if($rule->getVal('type') != RecordingRule::RECTYPE_OVERRIDE
&& $rule->getVal('type') != RecordingRule::RECTYPE_SINGLE)
            $override = clone $rule;
            $override->setVal('parentid', $rule->getVal('recordid'));
            $rule = $override;

         else if($timeLeft <= $conf->getOpt('sleep'))
            if(($end - $progend) < ($conf->getOpt('length') * 3600))
               $rule->setVal('endoffset', $rule->getVal('endoffset') +
               echo "Event isn't over.  Recording extended.\n";
               echo "Event isn't over, but it's already been extended
beyond the specified limit so doing nothing.\n";

Unfortunately the last I heard the guy that wrote this didn't have a
working Myth box so we're probably on our own fixing it.

Thanks for the info David.  I will reinstall MRE and add some test
power search rules and see what's going on.  At least I have an idea
how it should work now.  Unforntunately it takes awhile to debug since
you have to wait for a sporting event that goes over it's scheduled

I guess the rule can end the recordings early... not sure how that
will react with overrides...

And I wonder what happens if there are two recordings active using the
same power rule... can there be two overrides for one rule?
