yes, in the "timer rules" section you can set desired actions, from a lot of different situations.
record all episodes
record if episode number differs
record if episode name differs
record if description differs
record max once a month
record max once a week
record max once a day
blah blah blah...
several options for you to choose from so you don't have duplicate recordings.
i even have one timer rule set up for just a time slot. sunday sports always runs past the time allotted. so instead of recording 60 minutes from 6-7pm, i record a time slot for the channel i select from 6-8:30pm. now if sports runs over, i have the show i want (and the exciting ending of the game that everyone is talking about the next day at work).
