I have a brand new Dell 9100, Pentium 4 Dual Core, 3.0ghz, nec 3540 on the p-ata and the 80gb drive on the s-ata. It's running win xp pro with the latest service packs, and Nero Burning Rom 184.108.40.206
Very strange. I run Windows Task Manager, performance, and it shows two cpu. One CPU Usage History is almost 100% while the other is idling at 15%.
Do you think it has to do with dual core/winxp and nero's burning process? Or would it be dual-core/winxp and nero's encoding process? I have mostly been backing up movies using dvdshrink, which runs fast until it gets to the burning phase. I have also been turning mp3's into music cd's, and don't know if it's the encoding or burning that is slow.
Perhaps it's related to the NEC 3540? I don't know. I guess I'll just have to play around some more.
