I have seen some posts about testing the accuracy of burns at different burn speeds using Nero DVD Speed. I downloaded it (version 0.53B), but I don't see any option for disc error checking.
I'd appreciate it if someone could point me in the right direction.
Run CD/DVD Speed and run the Disc Quality test. Always run this test at the same speed (I always run it at 4x). Look at the results, and see which burn speed gives the lowest error rate. If the error rates are close, then you can burn at the highest speed with confidence.
