Does speed affect the accuracy?

[Dave]

I would have to disagree and say that burning a disk at a slow speed is less likely to have any problems.

I have had some errors myself with some disks and have corrected them by reburning the disks at a slower speed with out making any other changes.

Don't think it's a resource or hardware problem, a P4- 2.4GHz with a Gig of Rambus and a SCSI Plextor should be sufficient.
If it's something important, I'll allways take the time to burn it slow.
