I have been backing up DVD's to VCD's for about a year now using TMPGEnc. I recently got a Sony DRU-500a burner and was hoping to back up DVD to DVD-R(RW)'s. I have spent several days trying a variety of softwares trying to do this and thus far have only successfully made to backups, both using DVD DECRYPTER and IFOEDIT. I can back up DVD-5s with no problem. I can back up DVD-9s to 2 DVD-5s with no problem. I have however not been able to backup a DVD-9 to one DVD-5 using DVD2ONE. It seems that when I rip in File Mode with DVD DECRYPTER I don't get any sound. I don't think it is a DVD2ONE problem. I checked the sound tracks when running DVD DECRYPTER. Any advice that anyone could give me on backing up DVDs in general or how to clear up the problem I mentioned above would be greatly appreciated.
