Burned 150 ritek white tops 8x on my lite on 832s no problem. Now when I burn it never makes to the end. The first 1.5 hours is fine then it freezes. Bought all disks at NewEgg. Got some Fuji's at Best Buy and they work fine. Comparing the disks after burn under halogen light the fuji looks uniform through out the Ritek looks to have stripes toward the outter edge. Is it the disks? Will New Egg replace them? I have gone through 10 trying to solve this problem. Any help is appreciated. Thank you.
