SPDIF would be outputting digital to your control pod.
This would be in the form of a single digital optical cable of a single digital coaxial cable. Either way would get you the same results.
For a source like a game or music, you would get a stereo signal to your speakers. This would play out the front L, front R, and the sub. If you wanted it to play off more than that, then you could use the surround modes from your control pod (PrologicII etc)
You wouldn't get true surround sound in games from that method, but you could still get output from all your speakers.
If you do digital you will get DD or DTS from your speakers though as the control pod can decode those.
So, surround sound from DVDs, stereo/fake surround for music and movies.
If you do analog, you'll get true surround sound from games, stereo for music (that you can still use surround modes on I believe), and your soundcard would do the decoding from DD sources like DVDs.
There's a few really long threads over in peripherals about the different connecitons techniques.
