Hi, I use Nero, and a week ago I started having problems with burning CDs. The Recorder Buffer empties all the time. The CDs still come out ok, but they take much longer and the recorder buffer empties and refills throughout the burning procress. The burning also effects the OS by creating pauses, everything responds a little slower. I've tried killing all the background programs: eMule, KaZaA, ICQ, Firewall, Antivirus, etc... I also disconnected from the internet - Nothing helps. I tried burning at lower speeds - That didn't help as well. Notice that I've been burning heavy for 6 months without any problem, and that it suddenly appeared (no, I didn't change the Nero version or install new drivers \ firmware for the cdr drive). I also checked the Task Manager to see if there's any process that consumes resources, but found nothing. What could be the problem? How can I diagnose it?
