Yes, thanks, I spent several hours (seriously) reading them -- I still 
disagree, but that will not get me very far.

I seem bound to accept hard padding and manually override scheduling 
clashes just so that I don't have to see-saw between recordings for the 
first and last minutes of a program. Given that is the case, I already 
know how to change the default record before and record after (which is 
under TV Settings > Recording Priorities, for anyone else who struggled 
to find it there) and how to turn off the soft padding before and after 
(why do we need soft padding after if it is only meant for powering up 
the tuner??), but I was hoping that someone could help me change all of 
my existing recording rules.

To save me manually going through and changing each Recording Rule, can 
anybody think of an SQL statement that would replace all "Begin this 
recording on time" and "End this recording on time" with 2 minutes and 5 
minutes respectively?

Thanks in advance!
