Yes it's exactly that - a "faux surround" mix. When I was playing the CD I really wanted it to rumble my bass speaker so I extracted the audio to a WAV file and processed it in Acid 4 as an AC3 (Dolby Digital) file. Add that to some NASA footage of the earth from the shuttle, add chapters & bingo.
I'd be interested in this as well. I've mentioned yousendit.com before -- it's a temp host server for files up to 1gb in size. It says files are available for a limited amount of time for a limited amount of downloads. I'm a member of a few groups who utilize this and have yet to been denied when downloading. It should also be mentioned that this Space 5.1 disc can only be played on DTS machines. This shouldn't be an issue these days, but I've seen posts in the forementioned dts newsgroup from people complaining they are only hearing static from these discs - this is the result of analog playback. The CD player must have a pure digital output (coax or fiber) and hooked up to a 5.1 receiver. One of these two must be able to decode DTS. It can also be played on a DVD player, but again, there MUST be a pure digital connection to your receiver. Standard RCA connectors will not work. to cover all bases, make sure your DVD player can play CD blanks. Some older models can't. -paul
