Inmiddels is het mij gelukt met de standaard tools in OS/X

dus applicaties als MTR heb ik niet nodig gehad:
Hoe ?
via google kwam ik uiteindelijk onderstaande tip tegen:
1. Select the disc in Disk Utility.
2. Create image > save as CD/DVD Master.
3. Change the filename extension (this ones gonna be hard for you) to .ISO
4. No, thats not 1S0, or 150
. its I-S-O. Think Im So Obvious as the acronym.
5. Change the extension by clicking on the filename, waiting about 1 second, then selecting the end of the file.
6. Then, where it says .cdr, change that to .iso. (No period at the end.)
7. (Or quotes.)
8. Then, this is the hard part, *click somewhere else* outside the filename to commit changes.
