i am a new limewire user. i have been successful at downloading
mp3 files, however i am having problems with other file types.

when i try to burn a .dmg file by dragging it to the blank disk it
said it was copying the .dmg file and after finishing the copying, i
burned the disk. when i tried to use the disk i had just burned, i got
this message:

you have inserted a disk containing no value that mac osx can read,
to use the unreadable values click initialize, to continue with the
disk inserted click continue. (there is also an eject option)

can some one please explain what this means? thank you in advance!
