I just downloaded Ubuntu 12.10 and I'm trying to put it on a blank DVD+R but when I open up Disk Utility and try to burn to my DVD, it keeps giving me the error "not recognized". The .iso is on my desktop. I'm running OSX 10.8.
Here is the error message from the Disk Utility logs: 2013-02-16 14:03:51 -0500: Unable to burn “ubuntu-12.10-desktop-i386.iso.” (not recognized)
How can I get this to work?
