[ubuntu] ISO burning issues

view story

http://ubuntuforums.org – I have an ISO that I'm attempting to burn to a dvd. I know the ISO isn't dead since I am able to run it in both WINE and VIRTUALBOX, but every time I try to burn it, it is no longer recognized when I put it in the drive. I've gone into the software center and downloaded every ISO archive in every language just in case, and have tried a few different burning programs. Some don't even recognize it. So far nothing works. It is supposed to be a boot disk...instead I have made several great frisbees. Any help would be wonderful. (Hardware)
