Ok, this is kind of a strange problem. I have never heard of this before. I got a 24x10x40 Mitsumi burner. I installed it and got everything working ok. Well mostly everything. I have been getting the problem of my audio getting really REALLY lagged when I try and burn something. I know I have used other people's burners and can do other things while burning, but not when I use mine. For example I have AIM open and set to play a sound when I get a message. It plays, but it is extremely lagged out and sounds pretty crazy. I also just found that when I was installing a game through my DVD drive it did the same laggy audio as when burning, but not quite as bad. I am using Windows XP Pro, Maxtor 40 gig HD 7200 rpm, AOpen DVD player, and AOpen AK73Pro(A) MOBO. This should be all the Hardware needed. I am also experienceing that buffer reduction problem that Didou was experiencing as well. But haven't tried that option yet. Any suggestions on enableing something, or changing something are greatly appreciated. Thank you in advance, and hope someone knows.
