DVD copy-on-the-fly slow, please help

Hi guys,

Can't fix this problem: I have two very similar computers, running exactly the same software. The one (3500+ AMD Athlon) will copy a DVD on-the-fly in about 13 minutes, the other (3200+ AMD Athlon) takes 43-46 minutes to copy the same DVD. I have tried re-installing Nero, but it didn't help. Also swopping the two identical Lite-On Combo's had no effect. Surely the difference in hardware can't cause such a huge difference in performance?

3500+ AMD Athlon 64 Socket 939:
- 2x 512MB Kingston DDR400 RAM
- 74.6 GB Western Digital SATA 10 000 rpm Raptor HD
- 160 GB Western Digital SATA 7200 rpm 8MB buffer HD
- Gigabyte nForce4 SLi Socket 939 MoBo (K8NU-SLI)
- Gigabyte nVidia GeForce 6600GT Turbo Force Edition PCI-Express
- Lite-On Combo Drive
- Lite-On DVD-RW


3200+ AMD Athlon 64 Socket 939:
- 2x 256MB Transcend DDR400 RAM
- 160 GB Western Digital SATA 7200 rpm 8MB buffer HD
- Gigabyte nForce4 4X Socket 939 MoBo (K8NF939)
- Gigabyte nVidia GeForce 6600 PCI-Express
- Lite-On Combo Drive
- Lite-On DVD-RW

Both PC's run Windows XP Pro with Service Pack 1a and Nero Ultra v6.6.0.1. All other software also the same.

Please help.
