virtualbox.org

I came through a problem today

Im testing some software on my Windows guest, virtualized on a linux host, and this software offered to create some bootable media, either floppy or cd/dvd.

The thing is that i am wondering now if virtualbox can take a blank image file mounted on the virtual machine, and burn any data on it........
If so, where can i get this blank medias?

Thanks!!

either floppy or cd/dvd.

floppy is easy done: attach an empty 1474560 byte file to the virtual machine

Ok, now, how to do for the blank cd/dvd?
