Anyone got a solution to this please. I have a selection of audio books on my PC which play on Windows Media Player without any trouble, but when I transfer them to my Xclef HD 500 the files become jumbled up, I have tried both right clicking on the files and "sending" to the player, and copying and pasting onto the player but it makes no difference. DMC (Xclef) are about as good as a chocolate teapot at resolving my problem. Somebody PLEASE HELP.
