DVD image manipulation via hdiutil

I recently used a pen drive to copy about 4GB of data from a Windows 2000 machine to my Mac. The idea was to back up this data on a DVD. Well, it turns out the Mac wrote the DVD using HFS+ instead of hybrid, so the Windows machine couldn't read it.

I thought you could select the format in Disk Utilities, but I couldn't find any way to do that. I eventually ripped the image off the DVD in Disk Utilities (creating a new image from the DVD), and converted it using the command line util hdiutil:

hdiutil makehybrid -o filename.iso -joliet -iso filename.dmg
This command converts the HFS+ format image (filename.dmg) to an ISO9660 image (named filename.iso), which can then be burned using Disk Utility.
