The reason I bring it up is that my system will be recording five shows 
at once while I am watching something else previously recorded when the 
previous nights 'delete' kicks in.  I would not want that delete to 
affect the five recordings or the playback.  Just wanting to know if 
MythTV was clever enough to just schedule the delete to after the 
simultaneous recordings, when the system is more idle.
