I bought a new computer, Sony Vaio laptop which has Windows Xp on it. Anyway, I ripped some of my cds with the media player so I could listen to my music. Later when I listened to them, some sounded normal and some were sped up alot. What could have caused this? I did listen to the ones I had just ripped while I was ripping the others. Could that have caused the problem. Any help appreciated.
