Heres my prob. I have had XP for about 3 mos. Started with clean install. No probs with CD creator after I downloaded the updates. Three days ago, I did another clean install. Installed CD creator the way I had before. My setup is still the same. Now whenever I burn a music cd, it fails due to a buffer underrun error. Anyone have any ideas. Think I might reinstall cd creator this afternoon and see what happens. I was thinking maybe it could be aspi layer related, but then why did it work before and also, data cd's appear to be fine. I know some of you fine people out there will have some good ideas.
