Bought myself a DTS audio DVD to test out my surround sound system... all I can say is wow... absolutely amazing. They play on any DVD player and sound great. I picked up the Tchaikovsky DVD from Best Buy for $20 and it sounds like youre in the middle of an orchestra pit. You get different instruments from each speaker and the quality is awesome. Next up, a Mozart and Beethoven DVD. Does anyone know where I can get an Opera DTS DVD?
