I was at www.nin.com and trent is releasing a remix of the downward spiral in 5.1. If you don't listen to Nine Inch Nails, he layers lots of sounds (a lot go unheard) in songs so 5.1 would be cool. Anyway I know there are DTS CD's but is that the only way this can be a CD. What can play DTS CD's, DVD players? I know he could release this album as SACD or DVD-A as well but those require me to hookup 6 cables to my receiver instead of the optical/digital coax output He does not say what format he is using for this album.
