No, I'm on a W2k system but I've banished the WinMediaPlayer because it has caused so many problems to my system. Sometimes if I browsed the internet and clicked on a WinMediaFile (.wma/.wmf) then my browser crashed while the player tried to play some tunes directly out of the internet without asking me to save it. So, I've decided to kill WinMediaPlayer.

On the other side I'm always working with .wav files (CD summery, studio, etc.) and so it was logical to me to use .wav files only. I'm using .mp3 files only for economizing my HDDs and for presenting them in the internet...
