    I've got a disk image that is refusing to burn to a DVD.

    I am aware of the fact that a DVD's TRUE Capacity is 4.377GB. I'm trying to burn a file that is 4.36GB in size. However, Disk Utility is not being my friend. :rolleyes:

    According to finder, my file is 4.36GB. Disk utility is claiming the same file is 4.4GB. Is disk utility rounding the size up, and therefore, not allowing me to burn the DVD?

    How can I get this to work?

    There's more than just filedata on a DVD that you create. When you burn a DVD, you not only burn the files but a "file table" that lists all the files on the DVD and where on the DVD each file starts, and other various information. This file table is probably running you over the 4.377GB limit.

    So the short answer is: you can't burn that file to a DVD.

    Get a Dual Layered disc and it should work fine. I think 4.35GB is the max for most DVD's.
