I have an NON copy protected data dual layer DVD. I need to put everything that is on the dvd on my hard disk then remove one file. After that file is removed I must write it back to a NEW dual layer dvd. I have just purchased a new dual layer writer and media. I also have Alcohol 120 software. Can anyone sell me how to accomplish this? I have been able to put an MDF and a MDS file with the data on my hard drive but don't know how to see or remove the single file.
