Well first off you didn't mention what kinda drive and firmware the unit is if your going to use it to burn. And some drive comes with ability to booktype the media to -ROM for compatilbilty and then some require a software to turn the drive to be able to booktype to -ROM media. I don't think you can change the layer break as this is part of the media disc but if you do a 1:1 copy or backup is will retain the same image as the original media. I done 1:1 backup of my media and haven't experienced to much problem with the layer break. You do know that dvd comes in dvd+5 and dvd+9, as most movies come in dvd+9 but if you have clonedvd can compress from dvd+9 to dvd+5. Also what movie are you referring to that has a different layer break to as after you backup the movie? I don't ever recall a layer break being different when you do a 1:1 backup of the original should save the formating and media image as the original media.
