Nero Version: 7.0.0.0 is buggy, update to the latest version.
The main problem is that DMA is off. Check the DMA settings of your drive. After DMA is on, check the result of the Nero CD-DVD Speed burst transfer test, you need a disk with some data in the drive to run the test. It should display about 23 MB/sec.
