Actually, any CD player with a digital output connected to a A/V receiver that can decode DTS or AC3 can easily use a normal Cd player and a normal Cd to play a 5.1 format. The Cd has to formatted via redbook standard so that the player knows what to do with it. The digital file is just a bitstream to the burning program.....As I said it works great on the PC side of things with Nero or Cd Architect, but I need something to work with a Mac. Toast version 8? I Think? used to do this just fine. You had to option drag in order to keep it from trying to re-encode. The Toast 10 manual (Pg73) indicates that this should be possible, but in practice, I have not yet gotten it to work.
