The setting you changed is a soft pre/post roll. It's suppposed to 
behave like that. It was designed for situations where you need the 
recording to start a little early because of some external timing issues 
(like waiting for a set top box to change channels, or warm up, etc) 
This topic is well covered on the main MythTV users list (you can search 
the archives at http://www.gossamer-threads.com/lists/mythtv/users/ )  8)

If you want it to use different tuners, then you need to set the end 
late time on each individual recording.
