Have any of you played around with the following technique?
A DD or DTS 5.1 soundtrack is cleverly converted to a stereo WAV file that is then burned to a plain vanilla (red book) audio CD-R. The resulting disk is played on DVD player connected digitally to a DD or DTS decoding sound system. The DVD player thinks it is playing a stereo audio recording of static and dutifully outputs PCM to the sound system that detects it as either DD or DTS and decodes it as a multi-channel soundtrack.
The technique and how the content is created is described more fully at
This is the only way that I'm aware of to contain 5.1 sound on a CD. Its pretty nice... you can download some wav files from the links in the original post, burn them to a 9 cent CD-R and play them on your DD or DTS system (but not a plain CD player). Its a blast... give it a try.
