Testing image compatibility

Testing image compatibility is important. During the work with dvdisaster you can (and sometimes must) use ISO images which have been created by third-party software. Unfortunately ISO images are only informally standardized. Typically all programs will produce the same images when advised to use the ".iso" file format, but it is better to make sure that a usable ISO image has been created: Processing a non-iso image with dvdisaster will result in unusable error correction data. Especially, formats like .nrg are not suitable for processing with dvdisaster.

Possible scenarios. The following situations require exchanging ISO images between dvdisaster and a third party software:

a) Creating error correction files from ISO images made by a CD authoring software

A CD/DVD/BD authoring software is used to create an ISO image. This image is used for writing the medium and for creating the error correction file. When using the authoring software for the first time with dvdisaster, make sure that the image was written to the medium without modifications.

b) Augmenting ISO images with error correction data

dvdisaster adds "invisible" error correction data to the medium in order to minimize interference with other applications. Therefore it is possible that some CD/DVD/BD writing software will not properly write the error correction data to the medium. Make sure that your writing software does correctly transfer the error correction data when using it with augmented images for the first time.
