repeat (re-run, previously-shown) detection

Does this software utilize the "first run only" feature of MCE?

It detects previously-shown

It detects previously-shown shows for the given days range, however I don't know abou the feature in MCE. I know the MCE has the show attribute "Premiere" which I never set (I don't know whether it's the real 1st time run), did you mean this attribute?
