An ISO file is an image file of the disk. It is a complete copy of the disk’s contents, with the exception of the encryption. You can leave encryption on using AnyDVD HD, but no one advises this.
To make an ISO with AnyDVD HD, start the program, then right click the fox icon at the bottom right of the screen. You’ll get a list of choices, one of which is Rip to Image. Click on that to make an ISO from the blu ray movie. ImgBurn can burn this straight to a disk of appropriate size by clicking Write Image file to Disc when you start up ImgBurn. Set your burning speed to 4x. If you have ImgBurn set to the wrong file system for blu ray, it will tell you this, and ask to set things correctly. Let it do so.
This process does not get rid of extras, like the previews and does not set the movie to play in a loop. So you’ll probably want to continue using Fab instead if you need those features. You might want to select movie only backups to save some space. Many blu ray movies that would have to be backed up to 50gb disks will actually fit onto a 25gb disk if you do a movie only backup.
Since I do not use DVDFab, I suggest starting a new thread in our DVDFab forum for detailed instructions on using the program with blu ray. Here is the forum you need to make your inquiries in: http://club.myce.com/f116/
Edit: By the way, you can’t mention AnyDVD in the Fab forum. , so leave out the part about using it when asking how to use the blu ray copy in DVDFab.
