Creating audio content in surround sound?

Question

I am doing some research in creating surround sound audio. I intend on creating 5 mono channels. My questions are:

1) How do I create an audio file with surround sound audio?

2) What codec/format will the audio be in?

3) What software for a mac will do the job?

4) How can I burn the surround sound audio to a dvd without it mixing back to stereo audio?

5) What software does that on mac?

Thank you.
