factors affect burning speed?

Often the drive will analyse the ATIP of the blank disk which contains info on dye type, manufacturer and burn speeds. It then won't let you burn any faster than the stated maximum speed in order to get the best reliability.

Also, defragment your hard drive in order to speed up the seek times, close all running programs that are CPU and/or memory hoggers, and maybe install some more RAM. These factors can also have a bearing on the speed.
