The option will be on the DVD player, not at the 950. With DVD-Audio, you will want to switch to 6 channel as grundrc posted, at which point you will be listening to the MLP DVD-A track, which is better than the DD and DTS tracks. Those tracks are included for backward compatibility with standard players, and you may have to dig through the disc menus to get them playing, at which point you could use the coaxial digital input on the 950 to listen.
