I assume you've got the global overrun setting on the backend?  This
is a soft setting and (as you've found) is overridden in the event of
a clash.  This is very usefull if you've only got one tuner.

With plenty of tuners however, you're better off setting the 'start
early' 'end late' parameters in the recording profile.  These overrun
settings will be enforced by the scheduler and will cause your other
tuners to be brought into play.

You'll find plenty of discussion on this if you look in the archive.
