OK.  This is pure speculation...  There are two ways to verify whether 
my guess is correct:  you can wait for someone who's much smarter about 
the inner workings of the scheduler than I am (i.e. Bruce Markey or 
Chris Pinkham or David Engel or ...) to confirm or deny it or--even 
better--try it out for yourself.

You /should/ be able to get the exact behavior you want without a 
"per-channel" start early/end late setting.  Assuming you want TNG on 
one channel to record an extra 3 minutes early and late, but on all 
other channels to record "normally" (i.e. using the global pre/post-roll 
if warranted), just make two recording rules.

The first rule should be to record all episodes of TNG on this channel 
(the messed up channel) with a 3-minute start early/end late.  The 
second rule should be to record all episodes of TNG on all channels with 
no start early/end late.  I don't think that Myth would pick the "this 
channel" rule over the "all channels" rule by itself, so you'll probably 
have to set the "this channel" rule to have a higher priority (i.e. +3) 
than the "all channels" rule (i.e. 0).  (Unfortunately, I don't know if 
"this channel" is considered a different scope than "all channels," so 
this might not work at all.)
