The first time you experience a movie in DTS-ES of Dolby-EX, you’ll want a multi-channel DVD player as well. Might want to think about biting the bullet for a used multi-channel universal player (DVD/CD) to hold you over for a couple years until HD players are available at reasonable prices.
I just watched a movie in DTS-ES that had a scene where someone was talking on a cell phone walking toward the viewer, and then walked off screen to the left side. The cell phone conversation continued down the left side, around and behind, then up the right side until the actress walked back on screen on the right side. It was like she walked all the way around me talking on her cell phone.
