Can I copy audio CD's to DVD?

I would like to make backup copies of my favorite audio CD’s. In order to save storage space, I would like to store the audio tracks on DVD’s instead of CD’s. Must I first convert .cda tracks to .wav files and store .wav files? Can I do it in one step? I use Nero Express OEM suite 3 with no name DVD burner. Thanks.

Audio DVD Creator should be able to help you out. You can get it here, but its not free. Should be able to do a trial version.
