Sorry, no such luck for sacd.
But for dvd-audio, if you don't absolutely need the high-resolution MLP tracks (quick translation: MLP = hi-res PCM), then you can access the dvd-audio's Dolby or DTS tracks. This will be obvious on the disc's menu if you play it on a dvd-video player.
But if played on a
dvd-audio player..........
To access the 5.1 Dolby/DTS tracks, go to the
player's set up menu and look for the option to play the disc as a dvd-video disc. The player will read the disc over again and the DTS/Dolby options will appear.
FYI: this may occur: on dvd-audio players while playing the MLP tracks, the player's digital output may be active, but 90% of the time it won't contain a hi-res PCM signal (probably a "downconverted" 48kHz/24bit one) and when playing a 5.1 channel MLP track it definitely will
not contain a 5.1 surround signal--it will only be the two front channels (don't ask--I didn't design this open format!
).
