Ever try to watch a multi-lingual movie or even a foreign movie or a movie dubbed in another language only to figure our you're totally clueless about what is happening. That's definitely happened with me. Fortunately, with most movie files you'll usually find its associated subtitle files.
Facing a blank screen in your videos? Or maybe you can't hear the audio playing? Today almost all avi movies are compressed with DivX, Xvid or similar codec packs.
Got that brand new music player that supports DivX files and you have the videos but in a language that, well, you need to read the subtitles. On the PC is it extremely simple as several media players have support for subtitle files. You can use AVIAddXSubs for adding the subtitles to your avi file.
