I've followed the guide on how to make a full back-up of a DVD using CloneDVD. For some reason whenever it comes to writing the actual disc it gets stuck on 0%. I've tried versions 18.104.22.168 and the latest 22.214.171.124 I've also tried burning the compressed video with Nero and also using DVDShrink and DVDDecrypter instead. Have I forgotten to do or download something? I'm using a new LG GSA4163B drive (Firmware upgraded to A104) and Ritek G05 DVD-Rs or Sony DVD-RWs (both types of disc have written perfectly other than this problem).
