Hi I am new to this forum and have a huge problem. For some reason which I didn't notice at some point I ran out of DVD-R 8x then tried to burn with 16x and I keep getting an error report. I have tried all different types and nothing that is 16x will work but if I put in 8x it does. The problem is that I can't find 8x. Someone told me they are not going to be around long. Does anyone know why I can't use 16x. Also what is burn proof and how do I know if I have it. I use anydvd and clone dvd. What is the difference between clonedvd2 and clonedvd? I have a slimtype DVDRW SOSW-852S last revised 6SU1. Thanks to anyone who can help.
