Can anyone tell me what I am doing wrong? Some of the audiobooks that I have tried to download from my PC onto my player are recognised by it and others aren’t. They don’t even show up on the play list. All are of the same format, all come either straight from CD or from Youtube. Some from both sources are listed and play fine, othere don’t show up at all on the player, but do on the file when I connect it to my PC. Any help or suggestions would be greatly appreciated.
