How do you create a DVD-A mix disc?
 

I've been collecting a number of DVD Audio discs and I want to rip single songs from them and make my own disc. Anyone know how? I also want to retain the 5.1 channels.

I only listen to them in the car and I don't really want to leave then in there. Most discs are out of print and would cost an arm and a leg to replace if they were damaged or stolen...

Also, the discs don't allow you to go to the next track using the car's controls which is annoying. I have to use the disc's menu to select tracks and the screen is blank while driving. Having a disc without menus would allow me to skip tracks.
