I have recently purchased a NWZ-e453 which I am very pleased with but have encountered a slight problem. I understand that the player can recognise Itunes and play them but when I upload an I tunes audiobook file it willnot play. It has a m4b suffix, which is given as the Itunes audiobook format. If I change this suffix to M4a, the itunes default format, the file plays. All the reading that I have done seems to indicate that the same codec is used to play both these files, them4b suffix just telling an iplayer that it can be bookmarked. If this is the case I dont understand why I am haveing a problem. Can anyone enlighten me please.
