If you have 2 tuners of the same type, you can schedule the consecutive 
recordings before any others in those time slots. The 2 will use 
different tuners in that case, preserving the pre-roll/post-roll 
setting. If you want channel 2 both from 8 to 9 and 9 to 10, myth can 
use tuners 1 then 2. But if you also want anything on any other channel 
in the 8 through 10 period, you should let myth use the same tuner and 
drop the pre-roll or post-roll.

I didn't use these settings until very recently, and it was instructive 
to schedule some consecutive programs and see what myth did to resolve 
the conflicts by looking at the 'Upcoming Recordings' page.
