OpenSubtitles is the best and biggest place but it doesn't always have the latest subtitles. Also it might time out sometimes. So would it be possible to add more sources be default to the application. Or can i add to the current version?
Good sites for subtitles are:
SubtitleSource - Your source for subtitles Addic7ed.com - Quality subtitles in many languages for TV Shows and movies. Subscene - International Subtitles for Films and TV Series
