All through my years in High School, I was really involved with the drama program, specifically with crew. Started in construction, moved to running, then to lighting, and now that I've graduated, I was pulled back to help out with lighting and multimedia, since I was really the main guy for all of that when I was there (although I learned it all from a German wizard...).
This year, the Fall Play production was The Crucible, by Arthur Miller, and since I am a film student, I was also tasked with taping the show for DVD. We've had professional companies come in and tape shows before, but usually just the Spring Musical, since that pulls in more moolah.
Anyway, Here is the setup I used, and I submit this for your consideration, in the hopes that you may glean some useful information from it.
Step 1: Equipment: Intro
I'm not going to make a list of "what you need", since it's entirely circumstantial, and you probably won't have access to what you 'need' (I know I don't.), instead, I'll list what I gathered and how it was arranged in the best way possible.
In addition to your physical equipment, you'll also need to have the basic knowledge required to run the cameras, and optionally, know something about "mise-en-scene" (it's french, don't worry.), which basically means knowing what is visually appealing to the audience (smooth panning, rule of thirds, etc. google it.).
You also may (probably will) need a second or third camera operator, depending on what your setup is.
