To me one of the best things about DVD Decrypter is the way that it writes ISOs. I used to use Nero to write from files and then one day I tried Decrypter to burn an ISO -- the difference was fantastic. So I wrote to LUK to say thanks and to ask why it should give a better burn. As I recall he replied that using it to write an ISO should give neither a better nor poorer burn. Anyway being superstitious I have continued to use DVD Decrypter to burn. I have tried ImgBurn but it "just doesn't feel right" . habit I guess ? but then I always defrag before a burn, I put the disk in the tray for 10 minutes to walm it up, you know all the usual superstitious nonsense..... and as long as disks continue to play and data is not corrupted I will continue in the same old way.
