You will be surprised that some of the laptops nowadays come
with better DVD/RW DVD Rom drives then those for PCs.
The CPUs you used might also make a difference in terms of the
burning speed. The free space left on your HD might also be a
factor in the slowness on your PC.
Like some of the guys might have already mentioned, you may be
running more softwares on your PC, like Norton Antivirus (this will
definitely slow down your burning) and other background
applications.
Hope this helps.
