hi everyone,
i recently stumbled over Burnaware.
When i make a backup of a 3D-BluRay via "Disc Backup" (which creates an ISO file) the size of that file is much smaller than the BluRay's real size.

So for example the ISO file is only 25GB.
When i mount the ISO-file as a virtual drive and check the files sizes of the *m2ts files in the virtual disk's STREAM-folder the files show up much larger. So the 3 largest *.m2ts files are already over 45 GB.
So the ISO-files created by Burnaware seem to compressed.
Is that normal?

Thanks in advance
