I am using the latest version of Nero Burning ROM 22.214.171.124, Yamaha Lightspeed CD-RW 16x10x40, ABIT NF7-S2G mobo, AMD Sempron 2500+ cpu, Kingston DDR400 512 RAM, Windows XP SP2. Norton Personal Firewall and Antivirus run all the time. I have taken care of adware with Ad-Aware SE and I monitor/prioritize programs and processes with Codestuff Starter so there are no extra programs or processes that are slowing me down. Everything is the latest version; updates, firware, etc. Also, my IDE drives are set to Ultra DMA.
Whenever I try to write a CD-R at 16x, 12x, and 8x my buffer instantly shoots to 98% and it doesn't complete before causing a buffer underrun and failing. I have not yet tried to write at a slower speed, but I shouldn't have to. I don't know if this problem is with the software or the hardware. I have replaced my CD-RW with another of the same model that my dad bought and gave to me because he upgraded. They both perform and have tested exactly the same. Also, I encountered the exact same problems when burning while using Roxio Easy CD & DVD Creator 6. I switched to Nero 6 after deciding that it would be much better. However, nothing has really changed and I have no idea how to reduce my buffer levels.
Something else strange is that when I monitor the CPU usage with Windows Task Manager during a burn, Nero is hardly using an of the CPU (usually 00, but jumps for moments to 03-06) but the overall CPU usage jumps from 4-10% to 50-70%. System Idle Process is always using the vast majority of the CPU and I don't know if that is normal or not.
NOTE: I have recently found that the only way to get a successful burn at 12x, despite the maxed out buffers, is to disable Norton Antivirus, use CodeStuff Starter to put Nero as a High Priority, run a simulation, and not do anything else at all...including moving the mouse. The buffers are still at 98-100% the whole time. This hasn't work every time, but more times than not. Still, it's not a decent solution and it's not the way these things are supposed to operate.
So, can anyone help me? What is going on?
