Hi all I have built a new computer for a friend and have found a funny problem. The Internal Combi CD/DVD drive with S!PWMx2 technology won't write to CD-R disc's and also it won't read "Mirror Platinum" 4.7gb DVD disc's that have been recorded on my computer. it will read a CD disc and a DVD disc off a magazine ok. both computers use Roxio Easy CD-DVD Media Creator 7, I have noticed some people on the net are having the same problem. any ideas how to fix this problem. mac this is the first time i have installed a combi drive because he said it was cheap. never again, i will stick to my Sony DVD and NEC-DVD-DL any-day.
