m3u issue is supposedly fixed, according to Cowon.
Fixed the error that certain M3U format was not recognized.
Functionality that recognizes M3U files that are created in PC.
M3U folder will be created in 'playlist' from the top menu of browser when you copy .m3u files in COWON S9.
COWON S9 recognizes up to 400 M3U files.
COWON S9 recognizes up to 400 lists in M3U.
ONLY support extended M3U.
