So basically you want to burn a DVD Video with a 24/96 Audio Track and no video track, that will play on a standard DVD Player. To do this all you really need is a DVD Authoring software package that supports 24 bit audio. I have successfully done this on a PC using Sonic Foundry's Vegas+DVD http://www.sonicfoundry.com/Products/showproduct.asp?PID=810
You can even download a working demo I believe.
