1 pointSome media players (e.g. VLC) can play incomplete files. A lot of movies have a few seconds of blackness even after the credits have finished. If that 1% represented that portion, you wound never know it was "incomplete". That aside: Under the Info tab, does the Downloaded: bar have a visible notch out of it? Although depending on the torrent's Piece size, you might not be able to tell that anything was missing even at 99% completeness.
