I rarely look at my full list of scheduled programs. Today I saw many duplicates, cancelled shows, and other entries that no longer apply. Does my DVR spend unnecessary processing overhead because of a long list of junk? What benefit would I get out of keeping my scheduled programs tidy?
About once a week I review my series and get rid of dead ones. Many times when I know series final is coming up I kill the series and set a 1 time recording.
