    I recently had reason to dig out my macbook's OSX installation discs and discovered that disc 1 could possibly be damaged. It sometimes could not be read upon insertion into the drive and would just be spat out. Only with several tries, I would eventually get a break and the system would recognize the disc and mounts it.

    I took the opportunity to use disk utility to make a image of the disc in the hope that I could burn it as a backup. The only problem is the image is larger than the capacity of a single layer dvd, and my superdrive is incapable of burning dual layer discs. My only recourse is to transfer the image onto a PC which can write to dual layer discs, and burn it there.

    Is what I am trying to do feasible? The disk image is in the format .cdr. Would a PC, with the "Imgburn" application, be able to write this to a dual layer dvd, and the result be bootable back on my macbook? Or is there any other simpler method to achieve what I want to accomplish?

    You could try to rename the .cdr to .iso and then burn it.
