I enjoy film downloaded from several torrent site. Those are mainly avi, mkv, mp4 format. Some of the film have hardcoded subtitle, but most of them not. So i used to download subtitle from other site. when the files are .srt file that is OK. But when subtitle files are sub or idx file i can't see subtitle. I use k-lite mega codec pack or vlc player. what i do to solv this problem.
