I've been experiencing this problem of very slow DVD burning speeds, of about 1.5X even when the target is set to 16X. When using Nero, I observed that the buffer level keeps fluctuating. The DVD which is supposed to burn in 7-8 minutes is taking an hour to burn. Config : P4 2.8, ASRock Motherboard, 768MB RAM, etc etc. Recent Change : New SMPS Please help!!!!!
