I have been using Imgburn to back up my ISO for DVD and BD. I had problem with Reservation Road with Imgburn and after a thread in AnyDVD, I downloaded a 21 days trial for CloneDVD and I was able to back up Reservation Road without problem now. So what is the different between Imgburn and DVDclone? Pro and con. I am only backing up in ISO format and want to know a bit more before I purchase the CloneDVD. Thanks for your input advance.
