Tefler, have you burned the tracks using cd r discs or maybe cd rw discs, (They can be used over again) but they dont tend to play in a home/car cd player. Most cd r discs will play on any cd player. Once windows media player converts tracks, then burns them, it should finish by saying complete, I experienced such a lot of problems when I first burned tracks, but trial and error sure do play their part...On the right side of WMP make sure it reads *CD Drive (E) Audio cd * if not change it on the drop down menu. my home cd player is 3yrs old and all my burned cds play on that, they even play on my cheapo one in the kitchen. good luck, let us know how you get on
