I use CDEX (find with google.com) to do this. I have no issue with WMP except it's not tolerate of errors and support is hard to find. If you want to keep trying WMP, see if your issue is noted at http://www.nwlink.com/~zachd/pss/pss.html and remember that WMP is intolerate of any CD error or a machine that isn't setup well.
