if i load 10 mp3 files (known to be good as they play in WINAMP from clip playlist when mounted MSC), in MUSIC folder, when i select Play All, it only shows 5.
also, if i use the UTILM3U utility to create a playlist, it shows 10 if i edit playlist file, but only cycles thru 5 on player.
Since Play All doesn’t show them, the missing files may not be MP3. The Clip determines the type of files from their extensions. You should make sure the file extension matches its format. Check out this similar thread, Mp3 files work WMA do not; there’s info near the bottom of the first page about a free program to help you figure out the file format.
The file names seem OK (simple ASCII characters). Of course, according to the "MUSIC" path prefix, the playlist must be in the Clip’s root folder for the files to be accessible.
