It depends on the software you are using how it burns.Here are some free burning programs you can download.

Youll need a burner that supports DVD-RAM ,personally i wouldnt waste my time or money on dvd-ram it corrupts far to easily for my liking, youd be better off with rw media or better still a hdd,either way whatever you put on it youll need to backup or risk loosing it
