Depending on the disc, you don't even need a DVD player. You must, however, have a DTS receiver, and your CD or DVD player must be connected to that receiver with a digital coax or optical connection. The original DTS CDs will play on a regualar CD player, or a non-DTS DVD player. I found it hard to believe myself, but after listening to two of them in my old player (non-DTS), seeing the DTS indicator on the receiver, and hearing the beautiful surround sound coming from my system, I'll testify to it. Problem is, DTS is re-releasing some of those CDs as DVD-A, so you have to have a DTS capable DVD player to hear the track.
It's hard to tell the difference, but here's what I've noticed: If the label says "DTS Music CD," or "DTS Digital Sound," it will work on a CD or DVD player. If it says "DTS Music Experience," it's DVD-A, and must be played in a DTS capable DVD player. These will have a DTS 5.1 track, a 2.0 track, and an enhanced track for DVD-Audio players.
