I'm pretty certain I could access it through pressing audio on the remote control. There's some quirky authoring on some of those R.E.M. discs though.
EDIT: Just checked, yes - just pressing audio during playback did it, but you can choose it through the setup option on the top menu of the disc too. I was using the DVD-A layer, are you?
