[mythtv-users] make a recording stop before the end of the hour

[Dana Hata]

Is there any option to STOP recording early in the same way you can
specify to start recording a number of seconds early?  I have a problem
with back to back recordings.  I have my recording settings specified to
start 120 seconds early, but the second (or third, or fourth, etc) 
recording (in a back-to-back scenario) can't start 120 seconds early
because the first recording insists on stopping at the end of the hour. 
I figured the solution would be to make all recordings stop early by the
same amount of seconds that they are to stop early, but I cannot find
any option for that.
