user4133: I have a folder that contains around 51 videos and another folder with their respective subtitles.  
I don't want to merge the folders into one folder so I was wondering if there's a way to store subtitle srt files location (or at least a folder location for all subtitles) in an m3u playlist file along with the video files locations. 
Note: Video file format is flv.

user-1: m3u playlists only contains links to the media itself that you're playing.
It doesn't actually consider the srt file at all. If the software used to play back the m3u file support srt files it will look in the same folder for the same file as the video only with the extension switched to srt.
You will therefor always need to store the srt together with the video file.

user15995: yes, VLC supports that with the EXTVLCOPT custom tag.
example:
#EXTINF:-1,Abenobashi ED - Anata No Kokoro Ni (In Your Heart)
#EXTVLCOPT:sub-file=/p/Documents/mus/lyrics/Abenobashi ED - Anata No Kokoro Ni (In Your Heart).srt
#EXTVLCOPT:subsdec-encoding=UTF-8
Abenobashi ED - Anata No Kokoro Ni (In Your Heart).flv

Note that the path must be absolute and remote files are (unfortunataly) unsupported.
Alternatively you may change the sub-autodetect-path in vlcrc and add more search paths.
