I don't see how this would only work for playback. Just highlight the files you want to copy on the DVD, click "Copy" in the Windows Explorer, then go to the hard disk folder where you want to copy them and click "Paste". Then you can edit them and burn them again from the hard disk folder to another CD or DVD. Maybe I am missing something, but I can't see why this should not work. Copying a .wav file from a data DVD is exactly the same process as copying .doc or .txt or .exe files from a data DVD or CD. You only need a ripper if you burned the wav files as an audio CD, as by this process they are transformed from wav to CDDA format. When burned as "data" they stay the same as on your hard disk, so you can copy them back without a ripping step.
