I've been noticing that many new albums are being released in the dual-disc format (e.g. Springsteen, Ben Folds). I'm not overly interested in all of the "extras" as I barely have time to watch the special features on my dvd's, but I am curious about the 5.1 mix that is included with some albums. My questions is this - is the 5.1 mix in DVD-A or can it be listened to with Dolby Digital and/or Dts? I have only a SACD player at home - is it worth giving dual-disc a try? Thanks.
