If you are planning to buy, you will not do badly with Sony BRC-300 or BRCZ-330 and RMBR300 controller. A three camera rig will be ~$13,000. Set them on tripods that support well, no need for pan/tilt. Mix with any of many switchers like the Tricaster or VideoTek. Record into stand alone DVDR Pan makes best ones.
Microboards DVD dupper or a Bravo printer/dubber. but 100 DVDs is going to take a few hours either way. Pre-printing then 10X1 microboards will do 10 copies in 10 minutes.

There are thousand of other choices for equip but the idea is the same.
The Robotic cameras above could be operated by the TD from the controller. take a look at one that I set up

This is a one man operation. see that I’m recording to DVD and stream and operating all three cameras, all the while operating the audio mix. Actually, we train students to do this in about 30 min.
