Although LW has a media player, don't rely on it. Use your best ones. Somebody else on the forum had the same issue but the isproblem was with their setup/config. After they burnt the tunes to an audio CD, it played fine on their home CD player & car. At present Lw's player is purely to check the music & shouldn't be relied upon as your main player b/c it seems it's just not up to scratch yet.If you want to see the other article:
