How do you burn DVD AUDIO's?

i can easily make copies of dvd audios that are less than 4.7 gb but i want to be able to make them for bigger discs also without losing any audio quality. i tried deleting the VIDEO_TS folder because i dont care for that and just burning the AUDIO_TS folder but they wont work. then i tried to burn one with the audio folder and the video folder minus the large files in the video folder and agin would not work. please help if you know of a program that does or know of another way! thanks
