Actually, the hard padding is the right way (along with sufficient 
tuners--both physical and virtual--for the intended amount of recording 
you do).  The "global" option you specified is a hack that won't work 
except at the beginning and end of a recording session (i.e. first show 
of the night for the tuner gets an early start and last of the night 
gets the late end).  It was meant to be used only to allow some "spin 
up" time for the hard drive and/or capture card (firmware loading, etc) 
before first use (or first use of the evening), not to record extra.

That said, it seems most people are abusing it (as a placebo to make 
them think they're getting more of a recording just in case).  Just 
please don't complain when you find many (most?) of your shows are 
getting recorded without the extra.  :)
