Burning .dmg to disk - not enough space

I had a problem where i had a 580mb dmg and wanted to burn to 700mb CDR… For some reason, Disk Utility prevented me from burning saying that the disk size wasn’t big enough. I ran the following command on a folder with the .dmg file and it converted it to an .iso. Disk Utility then allowed me to burn to the same CD:

hdiutil makehybrid -o isofilename folderwithdmg

This should create isofilename.iso which you should be able to burn with disk utility.
