My intention was to mark "Desperate Housewives: The Complete Seventh Season: Disc 1" as watched, but by mistake I clicked "Remove from collection". So no problem, I had up-to-date backup. When I tried to select that particular profile from "Restore specific profiles" feature it was a bit of a challenge, since all I could see was a bunch of profiles called "Desperate Housewives: The Complete Seve" so I had to guess which of 'em was "Disc 1" and with my luck, of course it was the last one I tried.

It's not fun to guess when you restore from back up and that data will overwrite your present profiles without comparison. Changing backup window size doesn't effect this field.
