What they're designed for is allowing a few seconds extra time for hard 
drives to spin up or STB's to start up the first time a capture card is 
used.

They're not designed to allow second-precision modification of all 
recordings.

That's a matter of the timings .  When you have non-instantaneous things 
that must be done to tune and record a show, you miss part of the 30 
minutes.  All the settings you're talking about will do is allow you to 
record a little extra for the beginning of the first recording and a 
little extra for the end of the last recording--and only in some cases.

See http://www.gossamer-threads.com/lists/mythtv/dev/21063#21063 and 
http://www.gossamer-threads.com/lists/mythtv/dev/21064#21064 for 
details--where the latter explains the missing 4 seconds (which will 
continue to go missing on all but the first/last recordings on a capture 
card).
