 The subtitles search is done by precisly **identifying your video files** by computing unique movie hash sums. This way, you have more chance to find the **exact subtitles for your videos**, avoiding synchronization problems between the subtitles and the soundtrack. But what if that doesn't work? Well, a search with the filename will be performed, but be aware: results are a bit more... unpredictable (don't worry, you will be warned! and you can even disable this feature if you want).
